***** “Water treatment facilities” *****
I live in town, this is a concern that I have yet to address. I need to install a valve so the City crap doesn’t back up into my house... the recent flooding we had did not create any problems for me but I know folks where it did...
If we have extended time of no power or flooding or a combination of the two it would be a catastrophe that would render the house unusable and contaminate preps.
Won’t be cheap but I WANT the ability to close off that sewage line (we have a Mortuary right behind us and that just adds to the yuck factor)
I understand cyber attack threats is one of the reasons NORAD is moving back into their Cheyenne Mountain bunker.
PS to myself
I know Water Treatment and Sewage Treatment are different ... it was just the one on the list that fit “Public Utilities”
I have my own Deep Well and can draw water Manually if need be (not much but with a little manual labor enough to get by with)
I wonder for those that live in apartments....I suppose we are screwed if the Water treatment facilities goes down. I mean no problem storing water for drinking but how about the you know “nature 1 or 2”?
There should be a cutoff valve both at the meeter (your side of it) as well as within your house, right before the pressure reducing valve.
Hope this helps. I ordered a Petersen Inflatable Pipe Plug to seal off my sewer (inside the house, in the garage) before the mostly-horizontal pipe exits the house (underground) and goes to the main. I measured the pipe diameter at a point where I could assure total isolation of outside flow to inside (or the reverse in normal conditions). These isolation plugs are one or two stage and are inflatable (with a bicycle pump) and used by plumbers to isolate sewer lines for work and testing. My literature says petersenproducts.com and pipeplug.com and they are in Wisconsin. Not cheap (about $100) but quality and failsafe if you position and inflate it properly (provided there isn't a substantial back-head of waste water that could dislodge it, which seems unlikely).
Good luck!
I’m not sure putting a valve on your gravity sanitary would be such a big deal. If you’re draining to a municipal main you should have a 6” gravity service that stubs out, usually close to the property line, but not always. I think a 6” valve, depending on the type, would be in the neighborhood of $300. I’d put it somewhere well onto your property so that if the municipality ever comes out to do work they won’t know about it. Preferably close to your clean out so if you do have to close it and there’s any debris caught on it, you can get a snake in to get the debris cleared and the valve closed all the way. Do you already have an idea of what kind of valve you’ll use?
Shouldn’t be too expensive to get an anti-backup valve installed (my grinder pump has one). I have friends who had raw sewage back up and fill their house with almost 8” of the crap - it was a huge task/expense to make the house livable again and they now have the ability to defend against a repeat.
