There is a dual check valve off the main line coming into the house in our basement. It is there for a make-shift sprinkler system that is hardly ever used. Because the basement ceilings are finished (Drywall) I had to open up a part of the ceiling. The check valve is in a tight spot, partially above a bulkhead, and so I am unable to cut one end of the pipe in order to try and remove the check valve altogether without having to take the entire bulkhead down. The big nut on this check valve, at the other end, is accessible. If I loosen this large nut which again, is accessible, can I simply remove the spring loaded mechanism inside the check valve, of course rendering the check valve useless, and then tighten the nut back on to the check valve. Therefore there would be no need to cut lines, add new lines etc etc. In other words, no real plumbing issues to be concerned about. I simply made it so that there is no backup of any pressure in the line and that section of pipe now becomes free-flowing so to speak.
This all started when the hot water heater was leaking water from the relief valve.
