Water leak Pentair superflo vst

dsgerman said:

Superfoods vat now 1 year old. Several issues including recent slow leak from outflow connector. Is this connection standard? Looks like it’s siliconed on connection. Not using outer threads as seen on parts on diagram with unions.
Can this still be tightened to see if control leak.
Unrelated issues with air bubble in pump lid. Stable size. Looks resolve with recirculate and backwash. Also noisy tagelus miltiport. ?spider gasket. No leak from water line.

Superfoods vat?
Loosen the union above the pump outlet, remove the pipe into the pump. Clean the threads in the pump and on the adapter. Wrap about six layers of Teflon tape around the threads on the adapter, add a slight layer of silicone sealant over the tape. Tighten by hand until tight, then add another half turn. Should seal the leak.
Valves don't make noise, but you may hear noise at them because of air being pushed through the system. If the inlet of that pump was plumbed like the outlet, it probably is a suction leak. Would be curious to know why the unions that came with that pump weren't used. They seal very well.
