Hi all. I have a plumbing fixture question. Just trying to flush the lines in my 88 bigfoot
and it seems the water heater bypass valves are not sealing. Antifreeze is leaking into the hot water tank and i can't build up any pressure to flush the rest of the lines. The bypass is made up of a whole bunch of pieces of the light
grey type of tubing and has metal rings that clamp the tubing in place. Is there an easy way to remove and replace the suspect valves. I have not worked with this type of tubing before and i assume you need a special tool to clamp the rings. Any suggestions would be greatly appreciated.
