I’m starting a new thread because I don’t want to steal the one on the gate valve..
The only time I would add a gate valve to anything is for flow control, with ball valves used for shutof. Gate valves can get jammed in place due to the pressure pushing them on to the seat. A ball valve has the pressure balanced on both sides of the rotation axis.
Im not sure why a gate valve would be in a septic line, and I wouldn’t expect a 2-inch line to a leach field built in the last thirty years.
My inclination if I found that in a system would be to take it out, and put in a straight pipe. If I replaced it, I would install a PVC ball valve in a box, with a scrap of UHMW, screwed to the lid with SEPTIC engraved in it.
Can someone educate me, as to why a septic line to the field would have a valve?
