Hey guys, I could really use some advice here as I deal with this sewer backflow during flashflood scenarios.
I planned to drop a gate or a check below the bathroom floor (via a wall access panel) in a tight space between the stack and the exterior wall. After tearing up the bathroom floor, I discovered a double wye was blocking the only place I could put it.
So now I'm outside, an 8-10 foot dig, but at least now I can fit both a check and a gate on the line. I have a couple of sioux chief deep bury checks (online order required two), and these are quite nifty for cleaning and servicing from ground level.
I also picked up this massive Nibco epoxy coated resilient wedge valve (PCR 619-RW) with push on ends. It operates VERY smooth but I noticed it has the rubber wedge as opposed to sharp knife gate. I don't think I'll have any trouble stopping whatever comes through that sewer with this, but could it be a problem that it's not a knife... And what about those push on ends?
Anyways, I guess I need to put in a manhole if I do any gate, correct? I'm trying to decide if it's worth it because that's a lot of work for me! Unless, do you guys think I could just put the gate down there and not need to service it? I could try to encase it to keep dirt away and then send some schedule40 up to grade for the key to access. Then maybe just turn it a few times a year to keep it moving?
Otherwise perhaps just putting in 2 Sioux Chief deep bury checks would be sufficient? I've seen that some of those PVC check lids can blow in high pressure scenarios, but I've also heard that the brass flappers on those heavy duty checks won't open sometimes. So that's why I like the idea of having a solid gate down there with the PVC checks... just in case.
Another thought... if I run into a 6-inch pipe, is it okay to just use a standard 4 to 6 inch fernco coupling? Would you encase the rubber couplings in concrete?
I really appreciate any feedback you guys can offer. Thank you!
