Using a Nature 2 system with the BBB method

Waterbear, I'm emailing you right now.

1. The motor was replaced last July by a place that rewinds motors. The original got hit by lightning.

2. I'm still not sure how to find the exact model number of my superpump.

Actually, at this point, what matters is what impeller and diffuser they installed. You can take a Super Pump case, and by changing out the impeller, diffuser and motor, make it in to any other Super Pump.

Do you happen to have the invoice from that work? It might show the part numbers for the impeller and diffuser, and if so, will answer the question definitively. As it happens, I doubt that the pump is the problem. I'm discussing the issue with Waterbear.

Meanwhile, you DEFINITELY need to check out your filter interior. So get out your sockets and ratchet and open the thing!

I'll get the part number for the impeller from the pool place Monday morning. I got a couple of unions at the store today. I'll cut the plumbing and dive into the filter interior tomorrow.

[PoolDoc]

You shouldn't have to cut *anything* to open the filter!

[tdkorson]

How do I get the top off without cutting the pvc pipes? They don't have a union. My intent was to cut the pipes and install a union.

Is it possible to loosen the top clamps and scoot the base out from under the controls and plumbing on top??

[PoolDoc]

My bad!

I'm sorry, I was confusing the S244T with the older bolted Hayward filter. Forget all the stupid stuff I said about that; I should have checked the model number. You still need to check the sand, but will -- as you knew -- have to cut pipes to check the sand in a top-mount filter like yours.

I opened the filter. What a mess. There was a huge channel from top to bottom 6-8" wide. Some of the sand was very hardened. No wonder no filtering was taking place. So now there is new sand, and the plumbing has couplers in it.

Pump will be running 24/7 for a while. In a day or two I hope to see marked improvement.

[PoolDoc]

Just FYI; often bad sand means you've been using things the pool store sold you that you would have been better off leaving in the pool store!

[tdkorson]

yes, in my case, 17 years of junk sold by the the pool company. I know better now. I'll let you know how the filtering goes now that the filter is working correctly.
