I have a one valve by-pass system. It has worked fine for the last 5 years. I know its the valve, as I took off the line into the hot water tank, held my thumb over the line while DW opened the spigot's
and the pink antifreeze came out the cold water lines only. Before that, all the antifreeze ran into the tank. I am trying to find out the best way to get the line off the valve to replace it with a new one.
I tried to get the line/tubing off the flair end of the valve but it would not come off. I am thinking of heating the line/valve with a hair dryer then pulling it off, there are 3 lines on the valve. I was just wondering how anyone else has taken the lines off of any flair end valve or any other flair fitting. I don't want to just pry it off with a screwdriver or twist it off with pliers if there is an easier way. Prying or twisting with pliers will probably screw up the line/tubing.
