Pool sand filter leaking
 

The output on my sand filter developed a leak. I think it's a seal that
needs to be replaced or cleaned and lubed but I need to get the coupling
apart to fix it.

It's 29 years old so the plastic is probably very brittle. Does anyone
have experience with removing the coupling and repairing the seals?

Here is the coupling:

It's a BakerHydro sandfilter.

Here's a blow-up:

I'm real worried about the coupling breaking when I take it apart. I'd
rather not replace the coupling but I'm aware it maybe inevitable. Any
tips appreciated.

Thanks

You mean the leak is at the tan coupling? If so, I would first try to
hand tighten the coupling to stop the leak. On my filter (cartridge),
the couplings are only hand tight / snug. You might order an O-ring
(seal) and replace it while the coupling is open.

Do you have all winter to work on this, or are you somewhere that has
swimming year-round?

Good question. If you look at the second blowup it's leaking on the top
of pipe number 23 so it looks (to me) like seal #22 is leaking. Problem
is the 29 y/o plastic. I can't twist it by hand. I'd need a huge wrench
to twist the coupling. There is a very good possibility it will break.

I'd use a strap wrench. You can get them at HD, hardware
store, etc. HarborFreight also has them in a set where you
can get a set for about what one would cost at HD.

Per Oren's advice, I'd first try to tighten it a bit to see
if that helps. They should not be over tightened though,
typically just a little more than hand tight is all you need.

If you have to remove it and replace the o-ring, then you
have to do what you have to do. I'd also consider how
much it's leaking. If it's a pint a day, with a pool, I wouldn't
worry about it.

Strap wench is a good suggestion. That's probably what I'll do.

It's leaking quite a bit.

I'm thinking I have to loosen the top intake and the bottom outtake and
pull the filter away from the pump to get to the seals.

If anyone has done this I'd like to know. Even after it's drained it's
going to weigh a ton.

Is there anything like WD40 for plastic? Something I can spray it and
let it soak for a while before I try to loosen the couplings?

Look at the O-ring.

Release the pressure in the tank before you open this up.

If anyone has done this I'd like to know. Even after it's drained it's
going to weigh a ton.

Does the filter have a drain plug at the lower end? Pull the plug to
allow the water to drain after the pressure is released.

Yeah there is a plug (blow-up #1 part #15) But the wet sand is still
heavy. The pool supply store guy said I have to take the sand out.
That's a major pain that I think I might be able to work around.

The thing I'm most concerned with is the plastic. If anyone knows how to
loosen this thing safely I'd really like to know.

Sometimes to save the pot you need to split off the nut, then cut the
pipe and install a new fitting nut.

I wouldn't consider using WD40 on PVC. It can't rust anyway. Just try loosening
it first.

You are making it a bigger problem than it is. You could try spray on 100%
silicone. (food grade?)

I had an old Tahitian filter with similar fittings. When they gave way, I
was able to add new fittings using glue in extenders and a little
replumbing. If you run into trouble, all is not lost. Here's a link:

supply company has these, not the swimming pool places or HD.

It is safe on MOST plastics, and useless on about the same
percentage. One thing you do NOT want to use it on is sliding pivots
on vinyl windows.

You will probably find that is already broken and in need of being replaced.

WD40 is a solvent i.e. damages some types of plastic.

Pool piping in this part of the world:
1. is dissassembled every winter
2. with a (rubber) strap wrench if needed,
3. and reconnected every spring,
4. using Teflon tape to seal leak-free (six turns on
the threads of plastic screw fittings, and three more
on the butt, says local expert Sam who is always right.)

Agree with all of the above, except the teflon tape. The
fitting in question relies on a specific round seal. You can
put all the teflon tape you want on the threads and it's not
going to matter. If the water gets past the seal, it's going
to leak around where the shoulder of the nut meets the
pipe regardless of any tape on the threads.

My suspicion would be that he may find that something is
cracked too that caused the leaking. Another common
problem with this kind of fitting is if either end was moved,
ie someone slammed into the filter or other side of the
piping. Ideally that connection should be made with both
halves free to move as it's brought together. Worse case
is if both ends are fixed so that when it's tightened it
can't come together perfectly aligned.

Is there anything like WD40 for plastic? Something I can spray it and let
it soak for a while before I try to loosen the couplings?

WD40 is a solvent i.e. damages some types of plastic.

Pool piping in this part of the world:
1. is dissassembled every winter
2. with a (rubber) strap wrench if needed,
3. and reconnected every spring,
4. using Teflon tape to seal leak-free (six turns on
the threads of plastic screw fittings, and three more
on the butt, says local expert Sam who is always right.)

The pool store guy is even more pessimistic. He thinks I need a new
filter. So it's a $1.50 part or a new $500 filter. I'm keeping my
fingers crossed.

Here is the coupling:

It's a BakerHydro sandfilter.

Here's a blow-up:

I'm real worried about the coupling breaking when I take it apart. I'd
rather not replace the coupling but I'm aware it maybe inevitable. Any
tips appreciated.

Thanks


Some very good news. Went to HF and bought a rubber strap wrench
($3.99). I tighten it just a tiny bit and the leak is gone.

The Home-Repair Gods smiled on me today. :)

It's almost 90 today. I run the pool year-round.

More like Yuma Arizona or San Diego or Miami.

It snows in Albuquerque 3 months a year does it not?

Although I understand the gist of your post :)

Yeah. It get's pretty dang cold in ABQ. I lived there for 25 years. I
bought my first down jacket there. The elevation in the heights is 1 mile.

I live in Austin now. It's quite a bit warmer here.

You mean the leak is at the tan coupling? If so, I would first try to
hand tighten the coupling to stop the leak. On my filter (cartridge),
the couplings are only hand tight / snug. You might order an O-ring
(seal) and replace it while the coupling is open.

Good question. If you look at the second blowup it's leaking on the top
of pipe number 23 so it looks (to me) like seal #22 is leaking. Problem
is the 29 y/o plastic. I can't twist it by hand. I'd need a huge wrench
to twist the coupling. There is a very good possibility it will break.-

I'd use a strap wrench. You can get them at HD, hardware
store, etc. HarborFreight also has them in a set where you
can get a set for about what one would cost at HD.

Per Oren's advice, I'd first try to tighten it a bit to see
if that helps. They should not be over tightened though,
typically just a little more than hand tight is all you need.

If you have to remove it and replace the o-ring, then you
have to do what you have to do. I'd also consider how
much it's leaking. If it's a pint a day, with a pool, I wouldn't
worry about it.

Get some now. I have been using it for some years. Great on electronic,
electrical stuff. Has a higher viscosity than wd-40 , so I also lubricate
sticky items, but does not get sticky. Out of the nozzle, it tends to foam.

I will. I used to get this stuff called SBG (Silcone Based Grease). It's
the only thing that worked on my Polaris hose O-Ring. I've tried other
silicone sprays but they don't work AT ALL. They make it worse. Normal
petroleum based lube works, but not very will. I'll try the Crc 2-26 and
see if it does the trick.

Never mind. I see he answered that in another part of
the thread. He tightened the fitting and it stopped leaking.
