Hello everyone, My roommate has a old Hayward DE3620 pool filter (about 9 years old). Whenever there is any kind of pressure built up from filtering it starts leaking pretty badly from the top assembly where the manual air relief valve is (after a backwash it does not leak for a bit until the...

Okay. DE is added (3 DE scoops) and filter is running. And best of all the noise in the pump went away!!! :-D Perhaps some gunk was lodged in there somewhere. Now the downside. If I turn the valve to "waste" it seems the pump sucks water faster than what is coming in. The pump basket pretty...

Hello everyone, I just cleaned some pool filters that hadn't been cleaned in over 5 years with the help of this forum. That post was here: http://www.troublefreepool.com/need-information-about-maintenance-of-pool-filter-please-t26969.html Now that the filters are all cleaned up and in working...

Thanks for the replies. I was thinking an acid bath was necessary because these filters have not been cleaned in so long. They had built up algae and old chunked up DE inside the filters even after soaking them overnight in TSP. While waiting for an answer on the acid bath I went head and spent...

Any takers on my above post? I don't like to "bump" my thread but I'd like to put everything back together and get to cleaning the pool but the 2 things above are the only things holding me back. (amount of acid and sight glass question). I know that doing an acid bath is probably easy and...

Ugh..okay so I just got back from Leslies Pool Supply (getting DE and o ring grease). I asked them about muriatic acid and of course they said they do not recommend it. I have 1 gallon of muriatic acid. I have the grids in a garbage can in 30 gallons of water. How much muriatic acid should I...

Thanks everyone for your help. I'm on the tail end now. The grids are all taken apart and soaking in TSP. (I'll probably leave them soaking overnight). I have a few questions before I can put everything back together. Question #1: Regarding the down spout "inside" the filter that attaches to...

Thank you sportsman for the link. It's not the harshness of any chemicals I am worried about (I worked in a chemical plant for 10 years "unfortunately"). I just want to make sure I don't mess up the filters in anyway. The roommates, while happy I am doing them a favor, would probably be upset...

The only thing that scares me about using muriatic acid is if it will cause any damage to the grids or filter. I suppose I'll give it a shot as the stuff from Leslies is way to overpriced for something I am just doing as a favor. If I mess it up..they would probably want me to buy new grids...

Thanks waste I'll give that a shot. Any recommendations on my other questions? The link you sent me says to soak for 3 hours with acid while the youtube video I posted says to soak for 12 - 24 hours. This is possibly due to it being muriatic acid on the link you sent me. I plan on using the...

Okay, so this morning I decided to dive in and pull the filter out and clean it. The filters had a lot of sand on them along with some other gunk. Didn't seem to be any DE in there but you really couldn't tell. The grids and filters all seem to be intact. I stood the filter up in the driveway...

Thanks duraleigh and I agree with you 100%. What brought me onto thinking about this task is I cleaned the backyard and it looks really nice "except" for the pool and it drives me crazy! :wink: I figure I'll clean the filters, add the DE and see if "maybe" it will provoke them to take better...

Thanks for your responses. As far as people actually swimming in the pool? Maybe about 3 weeks out of the year. They do the chlorine and shocker stuff. And sweep..etc. I think when they do the sweep to get the gunk on the bottom they put it on the "backwash" setting" so it goes straight to the...

Thanks a lot for your fast and informative responses. My only other question was: When you backwash the pool it drains to the street gutter. When you do this does it also flush out the DE? I'm just trying to get an idea "if" there is even any DE in the filter anymore. If the answer to the...
