    Replastering, Redecking, Replumbing 20x40 in ground

    My 33,000 gallon 20x40 in ground that was built in 1973 and fiberglassed in 1995 is getting an overhaul. We are doing architectural work that requires removal of the pool decking as well as relocating the pool equipment pad. The pool leaks heavily at the tile line, the fiberglass is blistering...

    Old fiberglass on gunite, replacement options?

    Our gunite pool was built in the early 70's and eventually it was fiberglassed in the 90's. However, it doesn't appear the fiberglass extended to the coping rather it terminated below the waterline tile edge. As anyone can imagine, it appears to leak through the waterline tile and may well leak...

    20x40 circulation patterns, linear or circular?

    For a 20' x 40' rectangular pool, I would like to know what the more desirable circulation pattern is: A: Placing skimmers on opposing corners and attempting to set up a circular flow with the returns or B: Placing skimmers on the same wall and returns on the opposing wall for linear flow...

    Please identify this stuff appearing in > 20ppm FC

    My chlorine injection (see signature for details) strategy failed me while on vacation for a couple weeks this summer as I misjudged the frequency I would need someone to refill the reservoir and we sustained particularly high temperatures and wind bringing smoke from all of the California...

    Automatic Cover Recommendations?

    I have a 20' x 40' in ground rectangular pool with concrete decking. There is a very good chance that I'm going to be building a large structure near enough one end of the pool that the decking on that end will be entirely rebuilt with a greater elevation to the waterline. However, this...

    Hydro-Valet replacement

    Is anybody familiar with the 1970's era Hydro-Valet spa jet (photo at bottom of post)? I have three of these jets in an attached in-ground hot tub which don't appear to work properly. It actually appears that a prior owner may have reversed the flow on one of the three to utilize it as a...

    Perfect little brown circle stains

    Please help identify the source of this stain. I've included a quarter for scale. These little brown circles exist in a few isolated locations in my pool but in particular there are about twenty or so of them near the South West corner in the deep end. They look like little the remnants of...

    Suction Side Underground Leak... verified by photos!

    I've battled a suction side leak since I purchased this new home which has a pool as seen in my signature and my introduction thread. With a mechanics stethoscope I was able to narrow down the potential location of air intrusion downstream of skimmers to two possible locations. One at the NW...

    Newly acquired 1970 trouble full pool

    My wife got her wish, a house with a pool. I got what I expected, trouble. Neither of us is particularly excited about the magnitude of the pool. I think we've already tracked down the approximate location of a fairly significant suction side leak under concrete decking using a mechanic's...
