Quick question for this community. We’ve had a surge in the more-menacing, biting, water bug (not the harmless boatmen). Anything to help rid pool of those guys??

Bought my house 5 years ago and can only assume pool multi-valve was new then (can’t be sure). Looks like I’m leaking at bottom waste-output piping. Tried tightening the big screw but to no avail. Is 5+ years about par for the course for these things? Next step I guess will be to disconnect...

I have a Dolphin S200 vacuum … around a year old. This morning I turned it on and it started rolling through its initial diagnostics (rolling 1 direction then stopping before normal operation). Upon normal operation, unit moves forward incrementally then stops and this process repeats before it...

Hey guys, my pool went south very quickly this last week and developed a ton of green algae. It’s to the point now I can’t see my robot pool vacuum when it’s on pool floor. I’m brushing daily but the algae is not fully settling on floor & walls of pool. It appears to also be strongly suspended...

Are most impeller locking bolts regular or reverse thread?

I’ve decided to spring for a new pool cleaner - gonna get a Dolphin S200. Question: what is the IDEAL way of storing unit when not in use? Do you guys leave unit in pool when not running, or is it ideal to take cleaner out of pool after every run and allow for drying? What is best for max...

I have a Maytronics Dolphin (I think it’s a DX4?) that has been having problems of late with startup. I’ve read previous threads that led me to check the impeller. In past, checking/clearing the impeller resolved startup faults. Recently, startups are sometimes still problematic, despite cleared...

I recently changed out the sand in my Pentair Triton II sand filter. When purchasing the sand, the pool house person suggested some sort of cleaner that should periodically be backwashed through the filter. My gut tells me that no extra chemicals are necessary beyond a good ole plain periodic...

I’ve been using some cheap shock and it must not be buffered well or at all because after a couple of days, no chlorine left. Any recommendations on a more-premium buffered chlorine alternative?

Pieces of plaster coming up from pool floor. Any clever way of repair without having to drain pool and start over with fresh plaster/paint? I have tried 2-part epoxy and that worked in some areas but the problem is worsening. Thoughts?

Just noticed today that my pool pump sometimes loses prime then regains and cycle repeats. I made sure no air lock within my sand filter by releasing any air in system. Also checked and cleaned all skimmers. What is typical cause for this issue?

Never seen sand filter pressure gauge exceed 10 psi. Randomly looked at it while running today, was 40 psi. Immediately backflushed for several minutes. Won’t go below 40. I purged air valve near gauge, won’t go below 40. Any chance the gauge is fried? Hard to believe i built that much pressure???

Not sure what’s going on. Not seeing water flow through pump filter basket. Pump turns on and sounds ok to me but no flow. I removed basket cover and manually pour water and it seems to pump it but when shut off, water back feeds into basket. Not sure what’s going on? Need help.

Pentair Challenger pump - motor was screaming, very loud. Rather than replacing bearings, I opted to replace motor - Centurion Pool and Spa Pump Motor - B2854. Upon power up, post-install, the pump took a long time to prime and once running, did not seem to push water as strongly as one I had...

Pentair Triton II sand filter, 2” Pentair multi port valve (261055). Pump is off and I’m hose cleaning my sand filter with intention of overflowing bad water out manually, via open sand filter top. Can’t seem to find multi port option that allows water to overtake top, without somehow allowing...

How often should I be backwashing my sand filter and for how long, typically?

It seems as though my pump (Pentair Challenger) is running louder than normal. I keep the filter basket emptied weekly. Also noticed an issue in which my multi valve has a pinhole leak, which is another issue requiring some repair. Other than basket checks, I have never broken pump down further...

We have an in-ground trench drain that spans about 20’ or roughly the length of our pool. The drain cap is white plastic with holes and maybe an inch or two across. It’s a haven for weeds and needs attention. The cap does not just come off. Not really sure how to start over without tearing up...

Hello all - l'm seeking a good value automated pool vacuum. Last year, I thought I was getting one but didn't get chance to purchase - but was told that the S200 or Active20 were best value brands. Now that a year has elapsed, is there any other models you guys prefer that are value-priced...

Just slammed my pool. Have achieved good water clarity and only lost 1 ppm chlorine in overnight test. My current FC level is 25. Kids wanna swim today for Memorial Day. Is water dangerous for swimming?

With bleach in such high demand, I guess I'll go back to shock for the pool for next several weeks. Any web sites with great pool shock deals happening right now? Thanks

This forum has been very helpful to me in past with algae issues. I did a SLAM a few months ago, followed instructions religiously, and was very successful in turning my pool around. Since that slam, I do not introduce any new CYA in pool and maintain a current CYA level of 4.5. I use liquid...

What is the best pool robot/vacuum for the $? I need one that can climb walls. Also, what are some things I SHOULD be looking for with one of these things? I’ve been manually vacuuming for a year and considering a Christmas gift to myself this year! Help!

I recently drained a good portion of my pool in order to refill with fresh water and reduce my CYA content in the pool. In future, is this best way to reduce CYA or are there chemicals nowadays that can lower CYA without losing water?

I have a Taylor K-2006 complete test kit. I'm in mid-SLAM of pool and just realizing my R-0871 FAS-DPD titrating agent is near depleted. I planned to go to local Taylor rep in town and pick up new bottle but got a funny look. It seems everyone around here talks in terms of K-2005 kit and...

Drained pool by roughly half to start getting cya levels back normal. Noticed this wall separation when I returned. Will/should it resolve once water filled back in? Or is this now a repair situation? Also, there seems to be water behind the liner. Help!

In ground plaster pool, 40,000 gal FC about 8+ now that I shocked last night pH 7.4 TA 90 CH 250 CYA 80 Stats all seem to be in line. 4 days ago noticed thin alge buildup so I brushed it and ran pump, hoping that would kick it up enough to send thru filter and let shock handle the rest. As of...
