That torque sounds more like it. What kind of DE filter is it? I've only owned Pentair DE filters. A 20 yr old one a brand new one. Both had a spring under the band clamp nut. That silicone lube would probably be ok, but better to ask a pro. I buy mine from the local pool store. A tube lasts...

Another thing to try is tapping the band clamp with a rubber mallet all around the filter as you are tightening to help it seat properly. I start on the opposite side from the nut and work my way around towards the nut in both directions. Most of the DE filters use a stiff spring on the band...

Another option is to wack off the existing pipe flush with the valve port and use a 2 1/2" 45-deg elbow over the valve port, then reduce back down to 2" to rejoin with the existing pipe. You will need to clean the valve port with sandpaper to get a clean glue joint. I learned that trick last...

My local pool store seems to be out of everything. No acid, no liquid chlorine,, luckily they did have lots of DE. I got my multiport valve off ebay for an ok price. Received it in 2 days. DE filter was estimated at 8 days, got in 6 days. 2 inch PCV fittings was a pain. Had to visit 3 different...

Got it all together last night. Everything went pretty smooth. Got waste line conencted using a 90 and a 45 deg fitting. Had to use a drain type PCV for the 45 deg elbow. It's very hard to find PCV fittings around here, especially 2" stuff. Had to hit 3 different box stores to get five 90 degs...

Thx for the replies. Think I have a good plan now. Multiport valve came with a short clear piece of pipe with male threads on one end and slip fit on other end. I think it's to observe backwash flow but not sure why it's threaded on one end. Don't see anything I could screw in to. I'd like to...

Don't think I have enough room for 3 fittings. After looking at it some more, if I rotate the filter I can make the heater connection using a portion of the old pipe. This will mis-align the waste line but I later realized that I can make a 90 straight down then a 45 over to waste pipe and...

New DE filter and multiport valve mocked-up in place. Good news is the RETURN port of the multiport valve is facing the heater now. Bad news is the heater input is misaligned by abt 1/2". Can't move DE filter the way I need to go since its as close to house as it can be and still get band clamp...

Still looking..

One tidbit I've learned is that the instant the pump shuts off, if there's a suction side leak. water will spurt out for abt 1/10 of a second. You gotta be paying very close attention and it helps to have someone else at controls while you're watching the suspect area/s. My theory is the...
