Swimming Pool Therapy for Accident Recovery


It should come as no surprise to my regular readers that injury rehab and therapy is appropriate in a swimming pool.

Because swimming in pools can build up muscles and is good for joints, water exercise is often recommended for rehabilitation.

You can understand why – swimming is an activity that increases strength and flexibility, in a low impact and safe environment.

Today’s Health & Aging topic on swimming and accident recovery will take the following direction:

  1. Injury and Rehab
  2. Specific Exercises
  3. Limitations and Exceptions

bluecrossInjury and Rehab

Physical injuries can sideline you and really interfere with your daily life. Rehabilitation allows your muscles and ligaments to strengthen and provide more support for injured areas.

For all of the varied injuries there are equally as many recommended exercises and activities to help you get back into shape. Among them, swimming seems to have a place in most accident rehab therapies.

Why are pools so advantageous? The buoyancy of water is a force that acts on the body to balance the weight of a swimmer. supporting the body weight. The buoyancy of the water protects joints, while water’s resistance increases the efficiency of the workout.

Water exercise is low impact, meaning it is easier on your body than many other exercises, with less chance of further injury from falls or stumbles. There are many injuries that respond well to water exercises and swimming.

Because swimming is not weight-bearing, it is exceptionally helpful for back pain. Utilizing different swim strokes or positions helps alleviate some pressure in the back, as the water can provide support. The backstroke is helpful for back injuries because you lie in a supine position as opposed to other strokes performed in a prone position.

bluecrossSpecific Water Exercises

There are specific exercises in the pool that do not require swimming. For those regaining strength during accident recovery, effective cardiovascular workouts in the water allow the body to heal while building muscle.

Stronger workouts may include deep water running. Deep water running is the safe alternative to taking it to the streets and offers excellent cardiovascular benefits when done at regular intervals.

Water exercises don’t need to be strenuous to be beneficial. Simple calisthenics in a seated position, back floating, water walking, or kicking exercises are all helpful.

Basic pool exercises for accident recovery focus on gentle movements in shallow water, with support from a therapist, the pool wall or a floatation device, such as a pool noodle.

Example Pool Exercises

knee-lifts-in-the-poolThe Knee-Lift is completed while standing on one leg, knee slightly bent, with your back to the pool wall. Lift the knee up, while holding onto the side of the pool. Lower leg and repeat with the opposite leg. Strengthens and stretches muscles in the leg, hip and the lower portion of the back.

The Leg-Raise exercise is much like the knee-to-chest, only you are stretching out one leg in front of you. This stretches the back and leg joints while building your core strength.

warrior-pose-pool-recoveryThe Warrior Pose is done while standing on one leg, at arm’s length from the pool wall. Lean far forward, touching chin onto water, and stretch back with the opposite leg. This exercise stretches and strengthens all along the body, from head to toe.

The Pool-Walking exercise has you walking back and forth in chest-high water. It works your leg muscles while exerting little impact below the waist, which is especially helpful to most physical therapy programs.

Water-Jogging is a low impact form of jogging. aqua-jogging-for-accident-recoveryThe rules of form on aqua jogging are to maintain an upright body position and a straight back, holding your core muscles tight. Bend the knees 90° and move the arms forward and backwards, without any lateral or twisting movement of the body. A floatation belt can be useful for this type of therapy.

bluecrossLimitations and Exceptions

Be mindful of individual limitations before undertaking water therapy, however. There are exceptions and conditions which should limit or prevent any water activity from occurring. Speak to a [real] doctor or medical professional before beginning accident recovery in a pool.

In many conditions, medical and/or health professionals should be present to offer guidance and support while patients are in the water. In all cases should another person be within arm’s reach to offer assistance.

Water activities should be avoided altogether in rare instances. These instances include fever, severe heart failure, incontinence or infection.

Entering and exiting the pool should be done with assistance, to ensure a safe passage across the pool deck and into the pool, as well as a safe exit to the changing area.

Get your swim on, America!

5-Step Hayward Pool Filter Repairs

DE pool filter cutaway Making your own pool filter repairs is the subject of today’s post.

I’ve outlined the 12 most common repairs that you may need to do at some point to your Hayward filter, or to any pool filter.

Simple hand tools is all that’s required to maintain and repair a Hayward pool filter, along with a few parts.

You also need to know some process about repairing pool filters ~ I hope these 5-step summaries are helpful.

Hayward Sand Filter Repairs

add-new-filter-sand-smSand Change: Replace your filter sand every 5-7 years, or sooner if your filter is undersized, or if it has cleaned up a few algae blooms. Jackie wrote an entire post about how to change pool filter sand, but here’s a 5-step summary.

  1. Drain the tank by removing the drain cap.
  2. Remove the top mounted valve or dome.
  3. Scoop out, or use a wet/dry vac to remove sand.
  4. Pour in new #20 silica sand, labeled pool filter sand.
  5. Replace valve or dome securely, start up filter on Rinse.

hayward-folding-lateral-umbrella-assemblyLateral Replacement: Replace your laterals every 10 years, or if one cracks, it is best to replace the entire set of 8 laterals. If sand begins to pour into your pool, the usual cause is one or more broken laterals – here’s how to fix it, in 5-steps.

  1. Drain tank and remove sand, as described above.
  2. Fold up the laterals vertically, or unscrew threaded laterals from hub.
  3. Snap in or screw in your new sand filter laterals.
  4. Cap the standpipe, and pour the sand back in, or use new sand.
  5. Replace valve or dome securely, start up filter on Rinse.

Hayward Multiport Valve Repairs

multiport-valve repairsValve Change: If your multiport valve begins to leak, or the handle loses tension, you could repair it with a new key assembly or a new spider gasket, or you could just replace the entire valve – in just 5-steps.

  1. Cut pipes with hacksaw, leaving enough pipe to reconnect.
  2. Unclamp valve from tank, wiggle and pull up to remove.
  3. Lube o-ring and push new valve on standpipe, clamp tightly.
  4. Wrap threads 4x with Teflon; screw hand tight, plus 1-1/4 turn.

  2. Use small flathead screwdriver to remove all of the old gasket.
  3. Place small dabs of super glue or silicone in the grooves.
  4. Press in new gasket, wipe off any excess silicone.
  5. Reassemble by replacing key assembly in the proper orientation.

multiport-valve-leaksCracked Valve Body: If there is a small crack around where the pipes screw into the valve ports, or where the pressure gauge screws in, these were over tightened, or had too many layers of Teflon tape (use 3-4 layers over clean threads).

  1. Obtain SuperGlue ® or a liquid 2-part epoxy, like Plast-Aid ®.
  2. Cut pipe on cracked port, or remove gauge and clean threads.
  3. Thread pipe or gauge into hole to expand crack to it’s widest.
  4. Squirt expanded crack full of Super Glue or liquid epoxy.
  5. Quickly remove pipe or gauge; allow glue or epoxy to set up.

Hayward Cartridge Filter Repairs

  2. Unthread the pipe(s) from the filter in/out port.
  3. Wrap new Male Threaded Adapter with 4 layers of Teflon tape.
  4. Screw new MTA fittings into filter body, hand tight, plus 1-1/4 turns.
  5.  Rejoin with pipe, a coupling or union, and PVC primer and glue.

hayward-clamp-band-filterLeaking Filter Clamp: For your safety’s sake, when you start up the filter, if the belly band holding the tank halves together or holding the multiport valve is leaking, shut off the pump immediately, and take these 5 steps.

  1. Remove clamp band and top filter half completely.
  2. Remove belly band o-ring, and wipe clean with paper towel.
  3. Replace tank o-ring and apply a thin layer of pool lube.

Cracked Filter Tank: If your filter tank has a pinhole leak, or a full blown crack, the only repair to make it to replace the filter tank.

For sand filters or older stainless steel tanks, it’s usually cheaper to buy an entire new filter. Newer cartridge and DE filters can replace either the top or bottom tank half, at about half the cost of a new filter.

Hayward DE Filter Repairs

de-filter-grids-DE Filter Grid Replacement: Every 10 years or so, DE filter grid fabric starts to break down and develop holes or rips. When one goes, the others will soon follow.

  4. Place the bottom spreader on top and work it between the grids.
  5. Replace the thru bolts and tighten wing nuts, pulling assembly tight.

DE Manifold Replacement: Another cause of DE powder spilling into the pool is a cracked top manifold, or missing air screen or sock. Follow instructions above for changing DE grids to replace the manifold.

hayward-perflex-nest-assyDE Finger Replacement: If you have a Perflex® DE Filter, you don’t have filter grids, you have Flex Tubes, aka ‘fingers’. Like filter grids, these deteriorate over time. You can replace just a few if needed, or buy the entire filter nest assembly.

50 Causes of Swimming Pool Algae

dog-days-of-summer-2Currently, the Dog Days of Summer Sale is running here at In The Swim, which reminds me of an old phrase – the “algae days of summer“.

It’s the time of year algae has been waiting for. As water temperatures soar into the 80′s, your sanitizer struggles to keep up – ideal conditions for algae.

But there are other causes of swimming pool algae. So many in fact, that I’ve curated a list of what causes algae to grow in pools. In most cases, it’s not just one factor, but a combination of many…

What Causes Pool Algae?

Water Chemistry Problems

  1. Low free chlorine levels, below 1.0 ppm
  2. High combined chlorine levels, above 0.3 ppm
  3. High pH levels, rising above 7.6
  4. Low calcium levels, below 150 ppm
  5. Low alkalinity levels, below 70 ppm
  6. Low cyanuric acid levels, below 20 ppm
  7. High cyanuric acid levels, above 100 ppm
  8. Very high total dissolved solids, over 10000 ppm
  9. Never brushing your pool; ≈ weekly
  10. Never diluting the water; ≈ annually
  11. Not shocking the pool enough; ≈ monthly
  12. Not testing and balancing the water enough; ≈ weekly

    Pool Water Contamination

  17. High levels of bacteria
  18. High levels of ammonia
  19. Dirty pool, lots of leaves, debris
  20. Heavy swimmer use, bodily wastes
  21. Mulch leaking in or blowing into pool
  22. Fertilizers carried in from rain or wind
  23. Run-off from nearby lawn or planters
  24. Sap and pollen from overhanging trees
  25. Urban pollution from cars and planes

    Equipment Problems

  26. Pump is overheating and cycling on/off
  27. Pump is too large for the pool filter
  28. Pump impeller is clogged or broken
  29. Leaking or low water levels, drawing air
  30. Stuck skimmer weirs, drawing air
  31. Air leak before pump, drawing air
  32. Poor circulation in a large pool
  33. Filter is too small for pool size or pump
  34. Filter cartridge not seated properly, or missing parts
  35. Filter cartridge or sand needs replacement
  36. Filter not running long enough daily
  37. Multiport valve is recirculating or bypassing filter
  38. Suction or return valves are closed
  39. Salt chlorinator cell needs cleaning
  40. Salt chlorinator cell needs replacement
  41. Salt level in pool is too low
  42. Tablet chlorinator is clogged
  43. Tablet chlorinator is air locked

    Other Problems…

  44. Rough concrete pool surfaces
  45. Gravel, plants or fish (!) in the pool
  46. High water temperature, over 80° F
  47. All day sun exposure, over 8 hrs daily
  48. History of persistent algae every spring and summer
  49. Dogs, ducks or other animals using the pool regularly
  50. Non-pool items in pool; furniture, bicycles, skateboards, shoes, fruit…

pug-in-poolIt’s often not just one thing that causes pool algae to bloom, but a combination of factors that come into play.

To sum it all up, keep your water balanced and sanitized, make sure your filtration and circulation is optimal, and keep contaminants away from your pool.

Shopping 100+ Swimming Pool Lounges

dreamstime_xs_37442927-gif-100-plus-pool-floats-2The summer heat is blazing, the pool water is warm, it’s the perfect time of year to relax in a pool float or lounger.

So, when my InTheSwim catalog came in the mail, it got me thinking that I need to buy a new pool float for summer!

Easier said than done, we have over 100 floating pool lounges to choose from – how did I narrow down the choice, and choose just one?

Here’s how I did it…

PRICE: I had to consider price, first and foremost. Of the 100+ pool floats, there are prices between $9 and $369 ~ so I needed to narrow the range. I decided to buy a really good pool float this year, so I gave myself a budget of $200.

TYPE: To make it easier, I split up the floats into 3 distinct types of pool loungers, and chose two of the best pool floats from each category that were in my price range.

I.    Inflatable pool lounges
II.   Foam chairs and lounges
III.  Pontoon type sling lounges


Now, I’ve had inflatable pool rafts before, and most of them don’t last a season or two, but we have some really nice inflatable pool floats, so I included two of them into my list for consideration.

Body Glove Dual Lounger

Price: $105   Type: Inflatable


Body Glove Lounger

With almost 25 square feet of surface area, this float is huge! Gonna need a big air pump for this one! (ugh).

The best features are the soft combed top surface, and it’s jumbo 66″x91″ size. This big float that will keep you (and a friend) high and dry.

AquaSofa Floating Lounger

Price: $125   Type: Inflatable


AquaSofa Lounger

Another pool float with room to share, the AquaSofa measures 68″ round, and 36″ tall. Comes with matching sofa cushions, carry bag and air pump!

Soft covered vinyl is very comfortable, and raised edge keeps you dry. Great for snuggling!


Foam pool chairs and loungers are made with a very dense, closed cell foam – virtually unsinkable! Foam chairs are lightweight, never need air, and are very durable, too.

Aquaria Aqua Hammock

Price: $105   Type: Foam


Aquaria Aqua Hammock

The Aqua Hammock is made with color saturated Aqua Cell foam, and unlike other foam floats with a vinyl coating, will not peel, chip or fade.

49×26″ is the perfect size for me, it’s easy to carry and always ready to go. Guaranteed never to sink!

Luxe Sunsation Foam Lounger

Price: $195   Type: Foam


Luxe Sunsation

You’ve probably heard of the ‘World’s Thickest Pool Float’ – it’s 2-1/2″ thick vinyl coated closed-cell foam, with built in headrest.

You’ll still get wet with this, unless you weigh 98 lbs, but it gives the most floatation of all the classic style foam pool floats. 72″x26″ size.



That’s what I call them anyway – those type of sling back chairs, with two air filled plastic pontoons for support. Lightweight, durable, and very comfortable, with adjustable back positions.

SunChaser EvaFloat

Price: $160   Type: Pontoon


SunChaser EvaFloat

I’m looking for something a little different, and the EvaFloat combines a high density foam seating area, with two streamlined pontoons.

Frame made of super strong tubes of rolled resin; will never bend, rust or warp. Keeps you mostly above the water, in a comfy upright position. 50″x32″ size.

SunChaser SunSoft Lounger

Price: $150   Type: Pontoon


SunChaser SunSoft

I think you can see what appeals to me about this float. Super thick padding gives this pool float extra points for comfy-ness!

Made of fast drying mesh fabric and filled with fast drying spun polyester, mated with the SunChaser streamlined pontoons and heavy-duty rolled frame.


Now I had it down to a list of six cool pool floats, and I was still having trouble deciding, so you know what I did? I bought them all!

Just kidding, but I did buy two, and have been very happily enjoying my Body Glove Dual Lounger and the Aqua Hammock.

It was only $11 to ship them to my house, and with a 10% Off coupon I found online 10OFF150, I got not one, but two pool floats, with my $200 budget.

Avoid the confusion of over 100 pool floats and loungers. and just choose one of these above for your pool!100-pool-floats

And now, I must return to the pool, to float away the day…
