    Less Chlorine, more Algaecide?

    I'm interested in it because I am paying $160, on sale, for what was an $80 product not long ago. Thanks for the info.

    Less Chlorine, more Algaecide?

    So what evils await me if I try this approach? Also, is there any reason not to use the algaecide and defoamer if I maintain a high chlorine level? Seems like good insurance. One more thing: I have never drained this pool. This is my 7th year here. The chlorine is a little low at around 2 ppm...

    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...

    Best Sealant for Pump Inlet?

    I have generally had very good luck here with tradesmen. I have done well here with garage door people, plumbers, arborists, AC people, electricians...a long list. But pool people here seem useless. I called the only two companies that supposedly trace pool leaks, and neither one has ever...

    Recommend Good Economical Cartridge Filter?

    Right now I'm picking up very fine grey silt which appears to be nonorganic. It's going away fast, so I'm okay with it. I really think the old filter shot DE everywhere, and I'm seeing the finer particles. Best guess.

    Best Sealant for Pump Inlet?

    This is the second pump I've installed, if memory serves. Could be the third. The reason that's interesting is that until I put unions on the current pump, I had never seen them used. Everyone--professionals--who installed pumps I later replaced has used plain old Home Depot slip fittings with...

    Small Leak at Pump Strainer Housing Gasket

    I believe I installed the pump in 2018. UPDATE: 2019. I greased it somewhat more than you suggest, not having seen your response. It is currently holding. Thanks. Hope I don't end up with an oily filter cartridge.

    Is getting a cartridge really an upgrade?

    I got a cartridge filter. I don't really miss shooting a bushel of used DE all over my grass. I don't miss unscrewing 8 clamps and lifting a 50-pound lid off the housing. I don't miss getting DE all over my arm while SLOWLY adding it to the skimmer. They say DE filters better, but if your pool...

    Recommend Good Economical Cartridge Filter?

    Today I am paying the price for failing to find a competent pool repair company last year. I thought the filter would take a while to clog, but it has filled up twice already in one day. I put a robot in the pool, and it blasts the silt into suspension, so the filter is getting a real test. On...

    Use Cartridge-Cleaning Solution While Leaving Cartridge in Housing?

    Thanks for the help. I don't have foliage problems now. The people who built this house made the bizarre choice of putting a concrete flowerbox full of dirt at the shallow end, and they put 4 trees in about 12 square feet. I killed the trees and burned them, and I am thinking of building a...

    Best Sealant for Pump Inlet?

    Thanks for typing all that. Above and beyond the call of duty. The leak is sealed, however, so I will not be fooling with it until I see more water come out.

    Best Sealant for Pump Inlet?

    Thank you for suggesting that. I see we are talking about two different things. The unions I bought did not come with O-rings. They were plain old pump unions from Home Depot. If I had known unions with O-rings existed, I would have picked some up. I don't know whether it's possible to stick...

    Best Sealant for Pump Inlet?

    Have you actually seen a pump with a union screwed into it? Maybe I should post a photo. The union O-ring is working just fine. That's not where the leak was.

    Recommend Good Economical Cartridge Filter?

    I thought I was missing out by not getting a large filter, but then I found out they take a lot longer to clean, so I'm not sure a bigger filter would be a good idea. Easy job twice a year, or miserable job once a year? My pool is recovering from a period of problems, algae, and all-around...

    Use Cartridge-Cleaning Solution While Leaving Cartridge in Housing?

    Thanks. I'm glad to see I don't have to use any weird chemicals that endanger the yard.

    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...

    Recommend Good Economical Cartridge Filter?

    This filter seems adequate. The pool was truly disgusting, and the cartridge took a while to fill up. The pressure gauge didn't really get to the "CLEAN" mark, but the flow was dropping, so I cleaned the cartridge. If it can filter a disaster pool without clogging right away, my best guess is...

    Small Leak at Pump Strainer Housing Gasket

    I lubricate gaskets, but maybe I didn't use enough. Should I really slather it on there?

    Good Robot for Silt?

    To follow up, the Nautilus Plus CC seems to be working fine. It does have one issue: it gets stuck on steps. You have to look at the pool occasionally to find out if it's sitting in one place. I think the best policy for a person with a nasty pool is to vacuum it first the old-fashioned way...

    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?

    Are you really an expert? The pump has a threaded union screwed into it. This is what leaks. You can't put a union on this pump without screwing it in. The O-ring on the union can't save the situation. I decided to try the tape-and-goo method. I taped the male part up and then spread the goo on...

    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?

    Good Robot for Silt?

    My pool has a bunch of problems that are just getting fixed now, so there is quite a bit of crud to be picked up. I have already cleaned the filters three times. It will be impossible to draw any firm conclusions until I can see the bottom.

    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...

    Good Robot for Silt?

    Since no one has answered, I'll post what I know. I got a Dolphin Nautilus Plus CC with wifi. I think wifi is completely stupid for a pool vacuum, but Amazon did not have the regular version. I didn't see Maytronics fine filters on Amazon right away, so I bought knockoffs from Sunrra. They do...

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

    The solution was simple. Remove the filter from the system entirely, turn it on its side, seat an O-ring, turn it over, and seat the other O-ring. Then reinstall the filter. It turns out the rings will stay in place without grease.

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

    I will see if I can do that. It's very hard to get any room to work because I did the pipes first.

    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...
