Ok so I know I have posted some filtration pics in here or somewhere but if anyone is interested finally got around to fixing the 21” poor mans ultima. Here is what would happen During backwash I would lose some media it would escape through the multi port valve because the holes are bigger than the media. After talking with
kendragon
he suggested using stainless steel wire mesh and attaching some how to keep media from getting through multi port valve. My First attempt I tried to make an umbrella and have it sit on the very top of the sand filter needless to say didn’t work. Took it all apart again and on noticed the multi port vale a small screw that attaches the lower cover to the multi port valve removed it and was able to install the mesh on the inside enough talking on to pics
