    Less Chlorine, more Algaecide?

    I just paid $340 for two buckets of chlorine tablets, and that was a great price for these times. I don't know if it will ever be reasonable again. I used to pay $95 for one bucket, if memory serves. I mean the stuff with no calcium. Is anyone out there cutting back on chlorine and relying more...

    Use Cartridge-Cleaning Solution While Leaving Cartridge in Housing?

    I stuck a Pentair cartridge filter in my system. Now I have to get up to speed on cleaning it. I thought I could just blast it with a hose, and that works well enough to get the pressure down, but I see people online talking about cleaning solutions. Do I really need that? I am not eager to...

    Small Leak at Pump Strainer Housing Gasket

    I may have fixed the leaky pump inlet on my system. Now I am concerned about the pump's strainer housing lid gasket. When I shut the pump down to fix the inlet, water came out in two places. The inlet and the gasket. Only a drop or two came out at the gasket, but that's enough to be an...

    Best Sealant for Pump Inlet?

    My pump is a Hayward Super Pump. It has a female inlet fitting, and the return from the pool screws into it. It was sucking air at the threads. I had used pipe dope on them, but I still got a lot of air. I cleaned everything off and used Teflon tape. Still sucked air. I went back and tightened...

    Used Pentair S8D110 Filter Worth Anything?

    Is there any market for an old pool filter? I removed a Pentair S8D110 DE filter from my system. The housing has a 2011 date written on it. The internal bags are several years old. I was going to take it to the dump today because I don't want it to sit here while people from Craigslist keep...

    How to Seat Inlet, Outlet O-Rings on Pentair Clean and Clear C-160318?

    I installed a Pentair Clean and Clear C-160318 filter. I may have had too much faith in the unions on the inlet and outlet. I figured the engineers had worked it out so it was simple to close them. Instead of sealing them up and then attaching pipes to them with glue, I attached the pipes first...

    Good Robot for Silt?

    I'm about to give up and get a robot. I have a little 34-foot pool. It's screened, so if leaves get in it, they were usually tracked in. I get a lot of dead spiders and little bits of debris, and right now, there is silt. I was thinking of an Aqua Products EVO 604. It looks like it's similar to...

    How to Connect Pentair Cartridge Filter to Existing Pipes?

    I got myself a Pentair EC-160318 filter. Now I have to install it. The installation instructions are consistent with the industry's obvious efforts to block amateurs, in that they don't actually tell you how to install the filter. I received a housing with two threaded female fittings on the...

    Recommend Good Economical Cartridge Filter?

    My pool is around 18000 gallons, and I want a flow rate of 40 GPM. It has 2" pipes. Can anyone recommend a good cartridge filter that isn't too expensive? Absolutely has to be a cartridge filter. Thanks.

    Help Me Choose a Cartridge Filter

    Can someone suggest a good cartridge filter, or at least the right size, for a 19,000-gallon pool with a 2HP pump? I have a 2HP Hayward Super Pump. The pool is in-ground. I have a Pentair DE filter with 53 square feet of area and an optimal flow rate of 80 gpm.

    Should I Get Rid of Pop-Up Cleaners?

    My pool seems to have a slow leak. It also has a complex system of pop-up cleaners on the bottom. These little plastic things pop up when the pump runs and, supposedly, push dirt toward the main drain. My dad's pool had a similar gimmick 50 years ago. His pool had ridiculous hoses that...

    Plug Overflow Pipe to Keep Water Level High?

    My pool was letting water out through leaks in the inline chlorinator. I permanently plugged it so no water can enter or leave the chlorinator. Now I have my sights on another problem. My skimmer has two pipes exiting it. I have never seen this setup before. I believe the second outlet goes to...

    Permanently Cut Flow into Inline Chlorinator?

    I have a CL200 inline chlorinator I inherited with the pool. I hate it. I n ever use it, and it always leaks. The surface that mates with the O-ring is not in great shape, and O-rings always go bad eventually, even if you use Viton (or what Internet vendors claim is Viton). I would like to get...

    Where do I Get a Black Plastic Screw for a Grey Jandy Valve?

    My pool has Jandy valves (grey PVC) with little black screws with knobs on the sides of them. I am seeing leakage around these screws, and some of them are clearly dissolving. Can someone tell me what these parts are called and where I can get them? Thanks.

    How to Deal With Drain Full of Plaster?

    My late father's house has been sold. The last time the finish was redone, the contractor got plaster in the main drain. My dad did not force them to repair it, and now the pool can't be drained in the usual way. Eventually, the buyers will need to have it drained so the drain line can be...

    How to Capture DE During Backwash?

    I have a feeling I'm asking about something people prefer not to talk about, but here goes. I read that I'm supposed to put used DE in a container and "dispose of it properly." How do I put DE in a container when it comes shooting out of a hose at 100 gallons per minute? I think I may dump my...

    Tough, Economical 2 HP Pump?

    My 2 HP Pentair pump is not doing well. The motor is making an interesting noise, and the housing has cracks which are too numerous to repair. What's a good economical pump to replace it? I just want reliability. It doesn't have to be wi-fi enabled or make espresso.

    Wire Brush Okay for Gunite?

    I've been using a wire brush on my gunite pool, and it seems like a lot of junk ended up in the filter. Is it better to use nylon? I'm afraid what's going into the filter is gunite. Amazon lists a lot of nylon brushes, but the ads say they're for vinyl pools.

    Green Stuff on Screen Enclosure

    My pool is screened in. The enclosure is bronze-toned aluminum. Green stuff is growing on the screens and frame. What's the best way to get rid of it? Is there a way to prevent it from growing?

    Vacuum that Catches Crud Before it Gets to Filter?

    Last year I wanted to vacuum my pool, so I got a cheap vacuum thing and a hose. Problem: the Crud I vacuum up goes into the filter, so I have to backwash and add DE every time I vacuum. Is there something better out there? I don't want an expensive gadget that cleans the pool by itself, but I...

    Reinstalling Sta-Rite S8D110 Clamps So They Don't Leak

    I am trying to get my filter to stop leaking. I try following the instructions (alternating sides as I tighten clamps), but the filter still leaks. Is there a trick to this?

    How do I Make Swimquip Slide Valve Stop Leaking Around Shaft?

    I have a Sta-Rite DE filter (S8D110) with a Swimquip slided valve. The slide valve leaks at the top. I replaced the O-rings, and it doesn't help. The O-ring that is supposed to prevent leakage around the shaft is a #014 ring. It goes up against the underside of the lid. There is no seat for...

    Generic O-Rings for Pentair Backwash Valve?

    Does anyone here know the specs for generic O-rings to fit a Pentair 14930 slide backwash valve? I don't want to spend $20 for $3 worth of O-rings, and I don't want to spend a week waiting for Ebay. If I have the specs, I can go to the hardware store.

    Output Keeps Dropping Quickly; Lots of Algae

    I'm new here. Hope this is the right area for this post. I have an in-ground pool with what appears to be a big Sta-Rite sand filter. I am having some strange problems. I got a little algae a while back, so I shocked the pool and brushed it. It cleared up and came back, so I shocked and...
