    Hi there,

    I just rejoined this forum. I used this forum aroun 2002 when I installed my in ground pool, at least I think this is the same site. Anyway, as my pool has aged, other problems have popped up and hopefully I can get some advice one here.

    Welcome!

    Currently, traffic from registered users here is quite low. And I don't really expect that to change any time soon. I'm trying to weed out some of the weak answers and distill the better ones into FAQs and general guides in each section. I don't really want to restart the process of having 30 folks giving mediocre answers the same 200 questions.

    But if you can tell me what you are looking for, I can probably point you toward the best sources.

    Upgraded membership and moved thread to the Forum Q & A section. You may need to log out and back in to see everything.

    PS.You can search use Google to search multiple pool sites, using Google's 'advanced search operators" to limit your search to specific sites. This page of mine will create the search links for you. Google knows my site -- and all the others -- much better than those sites internal search functions! And, if you need to post pictures -- of your pool, filter, pump, piping, what-not -- there are instructions on this page

    Hey Ben,

    You helped me many years ago as I was building and starting my pool. I guess now Iím having Ďold poolí problems as the pool is now 16 years old. I have an in ground, gunite fresh water pool using only chlorine and muriatic acid to balance.

    My issue is with my filter which is an old Pentair SMBW 2060 using DE. Water is dripping out of the back flush pipe while the pump is running and when it shuts off, it draws air back into the filter. If the air isnít bled out at next filter cycle, when it starts I get huge bubbles pushed into the pool until is settles down. I think with all that air in the filter while pump not running reduces the effectiveness of the DE and I have to change out the DE sooner than normal. Iíve never backflused in 16 years, always complete disassembly and flush with fresh water, grids and all.

    For the moment, Iíve capped the backflush drain with a threaded fitting so I can clean out the filter body when needed. I donít know if this will affect the filter operation or not. It seems the backflush valve at the base of the filter may be bad but I here theyíre tough to change.

    Putting a valve on the discharge line is an acceptable temporary repair, and will work indefinitely, so long as the valve leak isn't so bad that a large amount of water is bypassing the filter, when the valve is set on "filter".

    You can probably test this by adding DE via the skimmer: if some returns to the pool, you've got water bypassing the filter. If not, not.

    But the bypass would likely be worst when the filter is dirty and the resistance to flow through the filter is maxxed.
