Please help me pick a new DE Filter

[TheGoose]

Any opinions?

Blue White flowmeter in hand. I'll know for sure what my flow is in the next few days.

I'm sorry you are not getting any replies. I don't know specifics about DE models since I use a sand filter. Maybe somebody else will chime in here with an opinion?

Hey, Goose

I'm not sure you need to buy a new filter. We can discuss that later.

When you install the flowmeter, PLEASE be sure to follow the instructions for placement!!! (a flowmeter that is installed without following the "10/5 rule is just a waste of $ !)

[TheGoose]

Can you give me some quick tips? The directions that came with it were quite spartan. I assume you mean about the space before and after with no bends etc.? I should be able to do that.

Also the way it looks I just drill a hole in the pipe big enough for the pilot and then clamp it on with the gasket? Again, the directions were not very detailed.

Yep, that's how you install it. If you got the model for horizontal flow then make sure it's pretty close to vertical when installed. Install the meter where there is at least 10 x the pipe inside diameter before the meter and 5 x the pipe id after. Be careful when you drill to cut only the hole you need, there's not alot of extra for the gasket to seal on the sides. The instructions should specify the hole size.

I'm stunned that a 325# sand filter is too small for a 1hp pump and 18k pool!

I suspect you are going at it all wrong because that filter should EASILY be more than adequate, even oversized. I run a 1hp (full-rated) pump with a 200# sand filter and 19,000-20,000 gallons with no problems at all. I have a two speed and full speed isn't a problem.

So...it could be a damaged or defective filter, multivalve, or pump. Or the whole thing isn't plumbed correctly. But there's no way a 325# filter should be too small for any 1hp pump. So I'm thinking you are looking in the wrong place for your solution.
