Resist the urge to take a sample of water down to your local pool store. Start with Turning Your Green Swamp Back into a Sparkling Oasis While you wait for it to get delivered, you have a homework assignment. That will give you what you need while you are clearing the pool, and probably enough reagents for a couple of years normal use. Order a TF100 and at least include the XL option. To do that you need your own accurate test kit. We base our pool care system on accurate testing and only adding what the pool needs, when it needs it. When you get down to it, DE filters will filter much finer particles than other filters, that's why it's clogging - again, it's doing what it's designed to do.įilters will never solve a problem with algae. Even a little algae will clog a DE filter quickly. Like Dave said, the filter is doing what it is designed to do, filter impurities. Goes to show it could be almost anything causing issues. I was having my kitchen redone and they were cutting the wood on the deck. I couldn't see it until I stood directly over the skimmer and looked down the hole (after spending a 1/2 hour thinking it was other things). It wedged in bottom of the skimmer and was reducing flow. Turned out that it was a corner of wood molding scrap that must have flew off my upper deck, landed in the pool and floated into the skimmer. I did have air in my pump once and I couldn't figure for the life of me what was wrong. When it got super dirty the return line was barley pushing out water (though I had no air issues with the pump). It took several days of this to clear the pool. I would have cleaned it like 3 or 4 if I was home (was working). I had a tough opening one year and I had to keep cleaning my cartridge filter very often (twice a day). No flow out of return is troubling but if the filter is really dirty it can drastically reduce flow. If it's very minimal to no air that's expected but if you get a rush of air for 5 seconds or more it would seem that air is getting back in from somewhere. Wait a half hour and open the relief valve again. ![]() When you have a steady stream of water for 30-60 seconds you know it's just about all gone. Open the air relief valve with pump on, it will expel air and spurts of water as the air is released. ![]() Just a thought but have you tried the air relief valve on the filter after a period of time? When you get the system running to what appears correctly make sure the air is let out of the filter. So is this a filter problem or is it a suction problem? Or something else? Just to try it out I ran the pump without any DE after I cleaned it and it seemed to run longer, maybe 4 or 5 hours, before this happened. If I backwash the filter I will get another hour or so out of it before the same thing happens again. If I look into the pump basket the water will not be to the top as if it's not drawing enough water. If I take the filter out and rinse it off I will only get 2-3 hours out of it before I start to not get anything back through the return lines. There is also a spa that spills into the pool but there is not heater and looks to never have had one installed Nautilus NS DE filter (I cant tell what size it is but I think its around 50 sq ft) Polaris 3/4HP booster pump for Polaris 280 cleaner (both of these are also brand new) Pentair IntelliFlo 3HP variable speed pump (I replaced the old one since it was 20 years old and all the seals were leaking) We bought a new (to us) house in October and now I am finally able to get around to getting the pool functioning. ![]()
