Cartridge filter size

[cd]

I need to replace the sand filter I have because of a crack in the multi port. When Pool people installed last year I was kinda wondering why they put A LOT of silicone on one of the fittings in the multiport. I took the multiport off and disconnected the fitting to change the sand and found out why. They cracked the multiport where the fitting goes in. I think buying the multiport is almost comparable to switching to a filter in $$.

The pool is 12x24, 10K gallon, 1 hp waterway 2 speed. what would be the minimum and ideal SF size for a cartridge filter? I see everything from 50 to a whole lot.

Thanks,

A complete multi-port valve runs around $100 to $150. A complete filter runs around $200 to $600. You might only need a part for the multi-port, which would hopefully be less than an entire valve.

In general, when buying a filter, larger is better. I suggest 75 to 150 sqft, depending on your budget. Larger filters are more efficient and don't need to be cleaned as frequently.

I have a 2 speed pump, my cartridge is 150sf...I have about 13,000 gallons.

JasonLion, It's the multiport housing that is cracked so I would need another one. I checked some prices they run from 150-175 for another on. It's a Aquatools AT3120 200 lb 21". I'll have to do some more research this weekend.

I believe you want part #14 on this page, though there is some chance that I have the wrong valve.

I have a 21k gallon pool with a 420 sq-ft cartridge filter but my pool stays open all year around. I clean it about twice a year with minimal PSI rise.

In your part of the country my guess is that you only have the pool open for 3 months a year so I would go with at least a 100 sq-ft filter and at most 150 sq-ft so you won't need to clean it more than once a season. Also, this puts you in the range of a single cartridge filter which will make cleaning a bit easier.

I just checked and that's exactly what I need. I'll have to bookmark that website. for $56 definately a reason just to repair. How difficult would it be to replace? I'm pretty mechanically inclined.

Just an update. Ordered the part on last Sunday from Poolandspa.com. Called the place Wednesday to see if when it might be shipped out. Reply "still workin on it, just wait for our email call back Friday if you don't get anything". I called today and the nice lady said "it's at shipping and it might go out on Monday" Hopefully the shipping is quicker than the processing. As of today just trying to rig something to keep the water flowing so the water doesn't get worse than it already is. Had to go to the old favorite of JB weld today, will try to put in service Saturday morning.
