Not really. There is an O-ring that needs to be compressed to make a tight seal.Is there any adjustment with the filter's bottom bulkhead fitting? Can it be backed out enough to make up the difference? Or is that supposed to be threaded in all the way (to a positive stop)?
I'm working with customer service right now with INYO where I ordered the parts, hopefully they can get this figured out.Not really. There is an O-ring that needs to be compressed to make a tight seal.
It seems that the tolerances are a tiny bit off on the filter and the multiport.
If you can't force it in without causing excessive stress, you might need new parts.
Maybe tighten the bottom nut first and then use a heat gun to warm up the bottom pipe while pushing the top fitting in until it is fully in and then tighten the top nut and let the pipe cool.
Be careful not to melt or burn the bottom pipe.
Get good even heat.
I agree...just waiting on a reply from Pentair before I do anything.You might need a new multiport and bottom fitting.
I think that if you got both nuts started and then warmed up the bottom pipe, you could slowly tighten the nuts until they were tight.
It only needs to bend a little bit.
Thanks - good to know. I'm thinking I'll probably just go this route, just need a heat gun. Dealing with Pentair customer service on this now and boy are they slow to get back. Two phone calls and emails with pictures and I'm still waiting to hear back from one of their techs.Had the exact same filter valve combination. Found the same misfit. I tightened the top fitting and warmed the lower piece with a heatgun and tightened the lower nut. Fits perfectly now.
