    Pool filter pressure gauge stuck at 20

    I don't know why, but the pressure gauge is stuck at 20psi, today I opened the filter to clean the cartridge and still it shows 20psi.. has it gone bad? if yes, is it easy to replace ? Thanks

    Yes, replace it. It is simple, just remember to use some teflon plumbers tape on the threads when putting the new one in.

    Any suggestions for brand or from where to buy?

    Not really, They are inexpensive parts and can be found at virtually any pool store out there.

    AS 257 notes, they are readily available and pretty cheap. (<$10)

    This place http://www.directmaterial.com has some really nice liquid filled guages that are a huge improvement. I Think they are about $20 but I am sure glad I got one.

    We had a metal cased one with glass face that came with our Anthony Pool 25 yrs ago until it finally got so cloudy we could hardly read it so I bought a nice new one at my Leslie's store this year when we opened the pool and they only had one kind...plastic. I liked the look of it but it has never worked well. We have always had 12psi with clean start up and this one was always 10 but I could live with that but when turned off it rarely dropped to zero unless I thumped it and had to thump it to get it to go back up after being off. It has been sitting at 12 for several weeks and should have crept up more by now so today I decided to clean it out just in case debris got in there. Nope..clean as a whistle and I turned on the pump to let a blast come up thru the lid to clean out anything that might be in there. I could not get it to zero while off the filter no matter what I did and when I put it back on and started up it just sat there. So thankfully I did not toss the old metal one. Put it on and voila......it went to 18 which is about where I expect it to be many weeks after last backwash.

    So...does anyone know where a better quality gauge can be purchased that has been trialed and used by a member ? I cannot find anything except the plastic ones on the web. Thanks

    I wanted to get a liquid filled one but it said it was only good down to -5 F or something like that. It gets a lot colder than that here in the winter. Will it freeze and crack/break over winter or are they just saying that it is not as accurate because of the viscosity of the liquid (we don't use our pool at -5). I bought a cheap 60 psi gage to replace the small 100psi gage that was installed but it really sucks, that gage is full of water and condensation and is hard to read at times because of this.

    I bought mine from this site and I have to say it is really nice. I had the pool company out last week and the guy said it was one of the nicer ones he has seen.
