Help with Preasure

[johnNJ]

My wife and I purchased a home that has an Anthony & Sylvian concrete pool with a hot tub. The pool is using a DE filter and has a 2 H.P Motor, it also has a Pool Heater attached to the system.

Here's the problems

1) I get NO water movement on the top in the pool. the water flow coming out seems very minimal.
2) the pool skimmers just don't seem to be working fully, I know in my other pool you can see the water being sucked down in.
3) the pool has 2 returns, both 3/4in pipe in the shallow end only about 6in's from each other.

Everything works fine in the Hot Tub, even if I turn all the Hot Tub valves off to just have the pool isolated the performance increase very little.

Now, the DE filter preasure guage reads 20psi, no improvement to my problems after I backwash.

Also I don't have any air bubbles in the pump.

Anyone with any suggestions?

Thanks

John,

You forgot to give us your CYA and total Chlorine readings...just kidding, man.

You have the same problem, I have. You filter is clogged.

Not sure why because you didn't give enough specifics, but it could be a few things.

I plugg my skimmer in the winter- intentionally. Is your skimmer plug out?

Does your skimmer line have shut-off valve? Is it open?

My guess is that neither of these are your problem because you have 20 lbs at the filter, so it must be getting water from the bottom drain or your spa, just not the skimmer. But if this were the case and the filter was getting adequate supply (no cavitation at the pump-right?) then were is that water going???? You'd have good flow at the return...but alas you don't. Therefore your filter is plugged up.

Could be one big DE cake somewhere. A dirty filter nest or my last though, a return valve that might not be open.

Just some food for thought...

Break down and clean the filter grids may do it.

Any chance you use calcium hypochlorite? The few times I've tried this, it's caked into my de causing pressure to rise, wouldn't backwash off and I had to breakdown and manually clean it off.
