    Any disability tools/helpers for pool maintenance (less bending)

    Hi! I am partially disabled (it is very difficult for me to bend) and I use a few helper tools to make pool maintenance easier. I have “Skimmer Angels” to make the skimmer baskets easier to remove so they can be dumped, as well as a “Lidz Off” to help me uncover the skimmer lids without having...

    Hi, I have a white Polaris robot, I just removed it from the pool and it looks to be yellowing; I wiped it and the yellowing came off! It is a light brown ... substance?

    Submersible pump in closed pool needed in the winter?

    I recently bought a new house pool (IG vinyl, NY/USA), and last winter when we were going through the inspection process it had a submersible pump under the mesh safety cover with a flexible drain hose going into the garden. When we closed the pool this year, the tech said that is was...

    What is this thing?? Taped up pipe near my Polaris.

    I just bought a new pool (it came with a house attached to it) and found this strange thing in the garden next to it. It is really close to the dedicated jet for my polaris cleaner. It appears to be flexible PVC, and I am only assuming its part of the pool, as its taped the same way my previous...

    "Recirculate" pulls way too much water (+air)

    I believe my sand filter is clogged with pollen (it is no longer pumping water out of the jets), and I wanted to add some liquid chlorine to address algae until I can figure out how to clean the filter (just bought the house this week). I put the MP in recirculate mode to bypass the filter, and...

    Buying a vinyl IG pool in winter; pump submerged?

    Hi! I am planning on putting an offer on a new home with a vinyl-lined IG pool (in the winter/NY), and during a visit I noticed a submersible pump beneath the liner with a pump outlet running to the lawn. I've had my own pool for a few years, and the only time I had to do this was when I had a...

    Preventing mosquitoes in closed, uncovered pool?

    Had a local shop install a new liner last month, and they left the cover off. I don't have my opening scheduled for another month, and there are mosquitos breeding in the pool. I've asked the guy to come address it, but he is not responding. Is there something I can do, besides open the pool and...

    Does multiport 'closed' position isolate filter completely?

    I have a leak in my DE filter bulkhead (top pipe, dont know if thats inlet or outlet) that causes pressure loss and DE getting in the pool when the pump is off. I have tried to set the multiport valve to 'closed' after turning off the pump, but found that I lost pressure again overnight; the...

    Filter bulkhead connection leaks causing DE in the pool?

    When we installed my Hayward DE filter this season, There was a small drip leak in both attachments on the bulkhead (inlet and outlet), hopefully just o-rings. I stuck it on the TODO list, where it sits. I've just found a ton of DE in the deep end, after the pump was off for almost a week; can...

    Which measurements will SLAM skew?

    I SLAM'd my pool to open it (mesh cover; black water), I've had to do it twice over the past 10 days to get the water clear and kill all the algae. I just added 6gal 10% liquid last night, so FC is very high and so is CC (I can smell it). I just used my Taylor K-2006 to measure my levels. I...

    Intermatic timer pin jammed

    I found my pump off unexpectedly, and it turned out that one of the timer pins/trippers had gotten jammed behind the yellow dial part somehow. It was a big pain to pull it out, the back part of the pin was jammed into a gear or something. This was the first time I'd used the timer; when I...

    Effectiveness of 2in backwash hose around 1.5in pipe (outer diameter, fits)?

    From this site I find that the outer diameter of a 1.5in PVC is almost 2in (1.90in). Can I just slip a 2inch backwash hose around a 1.5 pipe with a clamp on it and call it a day? I'm about to glue a barbed hose slip, using a coupler, to a 1.5in PVC backwash pipe, which is way more work then...

    Removing the diving board (new homeowners insurance company) - light electrical box??

    Hi, Our new insurance carrier has some rules for diving boards that our existing IG pool just can't meet, so we have to yank it, AND remove the supports ("trip hazard"), or lose coverage. My question is about this electrical box that is between the supports - it has to be for the pool light...

    Ants living under pool deck, pushing dirt in and generally being mischevious

    I have an old steel, vinyl liner IG pool, a concrete deck surrounding it, with metal coping that is fixed to the concrete, and I have an ant problem. They are living *underneath* the concrete deck and swarming all over the expansion joints and the coping. It appears that dirt under some of the...

    Type of caulk to use for dirt prevention?

    I have dirt entering my (30yo) pool in one area; over the years the concrete deck has heaved/moved/sunk a bit and there is a spot where dirt from underneath/between two pads is coming through a space between two pieces of (aluminum bullnose) coping (they meet at an angle, and there is a gap)...

    Robotic cleaner, no GFCI? What happens?

    What are the implications of not using a GFCI circuit with a robotic cleaner? I was planning to use the exterior outlet designated for my old polaris 380 booster pump, now retired, for my new polaris P9550 robot. I am unsure if the outlet is GFCI protected (there is no button on it). I am going...

    Chlorinator makes sucking noise when pump turns off; air leak?

    When the pump turns off, my Hayward inline chlorinator (for tablets) makes a sucking/ gurgling sound for a few seconds. Does this indicate a problem/air leak in the system? I have no cavitation in the pump basket, and I don't lose prime while the pump is off, but I do have a small return side...

    Can a return side leak cause DE to enter the pool?

    Hi, I have a 'DE in my IG pool' issue. I have followed the remediation steps found in this forum and elsewhere, including: - fixing a suction-side leak (the pump now runs with no bubbles/cavitation once primed) - replacing the multiport valve - replacing (most of the) filter grids, the...

    Rusty skimmers; in-ground. Screws?

    There is rust in the skimmer inlets for my inground pool, it seems to be concentrated where the screws are: How can I manage this situation? I am worried that something is wrong with my chemistry. The other one is even worse:

    Filter standpipe (inside) joint sealant/caulk? Need to re-seal, unsure what product.

    I've had DE getting into our pool since last summer, and have finally found the culprit (after fixing a suction-side leak, replacing o-ring, then grids, then the manifold). The caulk on the far side of the standpipe had come off. I have to remove this caulk and re-seal the pipe to the elbow...

    Channel around pool steps? What is this thing?

    There is a channel around my pool steps, I am not sure what it's purpose is and I cannot find anything on the web. It looks like some type of channel/female that accepts a male .. something. Please excuse the algae, those stairs are a PITA! :P Thanks!

    Bonding wire broken at equip pad, urgency?

    During the winter my bonding wire broke off flush with the concrete equipment pad. I am planning on opening the pool early this season so I can do some work on the plumbing/install new equipment before the summer starts. Is it urgent that I fix the bonding wire before the pool is opened...

    DE in pool, replaced grids, what am I doing wrong?

    Hi, I have an ongoing problem with DE in the pool, and thanks to you folks, I have been able to make progress. However, it just recently got a lot worse, and my efforts are not yielding success. 1. Knowing that suction side leaks can cause DE to 'puff back' through returns, I have identified...

    Broken DE grid spines; big deal?

    Hi, I am replacing some torn DE filter grids and found two grids that have small plastic pieces floating inside. They are clearly parts of the grid spines, I can see where they are cracked. There are 3 small pieces in one grid, and 2 in another. Do I need to replace these immediately...

    Polaris wheel rpm: pressure or drivetrain? Was: 'Debugging' Polaris 380

    The wheels on my Polaris 380 (w/ 3/4hp booster pump) do not turn at all (0RPM) when I hold it out of the water (causing it to get stuck climbing). The bag, propulsion, and tail jets all work very well. I have removed the outer shell while the unit was under pressure and observed that, when...
