$5000 for a new main ball shutoff valve?
And a new PRV, but who’s counting?
Had a trusted plumber over to our, new to us, 1965 home for a different issue, and he noticed that our water pressure was too high. He said we needed a new PRV, which is fine, makes sense.
The dilemma arose when I casually asked if he could also add a new main ball shutoff valve to our quote. He looked at it for a bit, took some photos, and said sure thing.
Get a call the next day, and he and his superior come back over to take a look at the valve, and they both agree that there’s no way to replace it without drilling through the foundation. That would involve digging a hole on the exterior to access it, permitting with the city, yada yada yada. Boom, $5K estimate.
In our previous home, built in the 90s, I had similar replacement done by the same company, and it was no problem at all. No digging, no permitting, and the guy was done in less than a half hour soup to nuts.
So I come to the experts. Is there no way to replace this main valve without drilling through the foundation? I added some other photos for context. There’s a separate ball valve for the irrigation system, but otherwise, it looks like pretty standard plumbing to me.
Any insight you can provide is greatly appreciated!
