Okay, I pulled my pool pump apart today. Here are the results. 1. The impeller was not clogged or worn, but the diffuser O ring was practically folded in half. I took the motor to the pool store to see if they could replace the bearings. Nope! the motor was shot. Bought a new motor (1 HP, BTW)...

I have a pool service do the chems in the pool. Once a week, usually every Friday. He's been doing it 9 years.

^^Yes, when I go to the pool store on Sunday to have bearings installed in the motor, I'll take a test sample with me.

I would like to give everyone an update on my filtering situation. I now have exactly 6 lbs of DE powder in my filter. It turned out to be just shy of 10 scoops from my DE scooper, far more than I originally had. It's been filtering for 5 days with the proper DE amount. I'm still nowhere near...

Thanks, man. You've been a great help. :-D You've all been a great help. Thanks.

I think my next step, before tearing down the pump is to disassemble the grids in the filter and start over. I will physically weigh six pounds of DE and check how many scoops it is. I'm starting to think my DE could be low. (another reason for the low pressure) :?:

Yes, I added two more pounds.

renovxpt, You've been more than helpful, thank you. I already bought the gaskets and a pump seal kit, so I'll be prepared when I disassemble it. I'm curious, more than anything. I'd like the filter to work as my old one did. Question: Don't you feel that my pump is a bit weak, in that, it...

Thanks, renovxpt, but there's 2 reasons why I don't open the main drain. First, the Navigator gets stuck on it when it's open. (yes, it has a diffuser over it) And, second, there's not enough suction when the drain is open to run the Navigator. In fact, in order for the Navigator to get the...

Thank you all for the very warm welcome. It is much appreciated. I'll try to answer as many questions as I can. The "plankton" like debris that I was seeing in the water was more than likely, DE residual from my old filter. The grids in my old filter were cracked and letting the powder into the...

Scott, are you sure you have that right? I ended up taking my pot lid and strainer basket to my local pool store and they confirmed that it's a Duraglas pump, not a Duraglas ll. They said the Duraglas ll has a strainer basket that's about 2" longer than the Duraglas. Also, every picture I've...

So, I've decided to pull the pump apart and inspect the diffuser and impeller. I'm going to order a Go-Kit but I don't know if I have a Duraglass or a duraglass ll pump. Does anyone know how to tell the difference? The labels are unreadable on the pump.The Go-Kits are definitely different.

^^Thanks for the tips. I'm going to check the impeller the first chance I get.

Okay, here are some pics. The white stuff on the ground is DE powder, not snow. It's south Florida, after all. :-D

Scott, is it possible that the pump is just weak? It makes a metalic sound (almost like the impeller is rubbing on something) upon start-up but goes away after a couple of seconds. The pump basket is empty. Does the impeller wear out over time? I know the pump is old because the exterior of the...

Thanks, Scott. The pump is an old 1.5 HP plumbed with 1.5" PVC. There's no air in the pump basket. I think the pump is about 18 years old. I don't know how I'd check the impeller.

Hello, all. I've been in my house 9 years, now, and the pool has had a crusty old Pentair 8000 series DE filter. The filter itself worked great, creating stunning pool water clarity. It could clear a cloudy pool in about a half a day. I could no longer find parts for it so I replaced it with a...
