We had a clog in the kitchen pipes last weekend. We opened the “overflow” in the garage and used one of the rubber expandable bladder things to blow out the clog.
Now, every time we turn on the water, or flush a toilet, the pipes hum/groan. We also have a whole house water filter that has started leaking badly. As far as I know, we don’t have a pressure regulator on our home, although I’m not sure whereto fine it.
There has been no construction or repair work in the area.
