Can your filter be too large?

[kooldecker]

Hi guys and gals i have a buddyof mine that has a DE filter he
kept from an above ground he had. He said i can have it if i want it. Im all for it as im completely obsessed with clean water. But i juzt dot know ifthere are any downsides to a large filter. I will be getting a larger intex next year so imalso thinking about the future. Any thoughts?

I also jusg read in a thread that alot of ppl have oversized DE filters and they dont need to backwash at all . They just teardown at end of year. Is that normal ? Im thinking with the size of my pool this could mean i could possibly get away with no filter maintenance all season. ( drooling at idea) lol

Yes, a filter can be too large for your pump to backwash it effectively. Which only means you'd have to manually teardown the filter and hose off the grids, which you'd want to do annually anyway. Too big for the pool? No.

I guess thats what i meant. As in too big for the pool. Its the pump and the filter that he had before as a set. So mabye i should be asking can you have a PUMP too big for a pool ?

Yes. Either you will not be able to get sufficient flow through the suction side to feed the pump or the return may overwhelm the pool and cause water to flow over the sides of your small aboveground pool.

I can totally understand that but cant bothmof those problems be overcome with plumbidng mods? Im totally down with modifications im a skilled person and am trying to figure this out. Its more than likely ill install this next year. Only have about a month or so left and things are running like a clock i dont want to disrupt it lol. So i have the winter to figure it out.

A pump can be too powerful for a pool, creating a rapid current, or too powerful for a filter, forcing debris out instead of the filter capturing it. If the pump your friend has is 1-1.5 horse power you should be fine. It would be a little much for a 10 x 30 pool, but just fine in a larger pool. You may need to modify the pool to connect it to the bigger pump.

I was already figuring i was going to have to mod the pool inlets and outlets possibly. What i ay end up doing is mabye buying a smaller pump, and saving the other one for a bigger pool. With the free filter im still financially ahead of the game.

Years ago I plumbed a large spa pump and cartridge filter to an above ground pool and it moved the water too much. I solved the problem by changing out the impeller on the pump.

Be careful. Impellers are sized with the motor. You can burn up a motor or do other damage by using the wrong impeller for a specific motor.
