Freshwater Tank, Newbie Questions
There are three petcocks on the freshwater tank of my 23 footer. One is white plastic, located on the lower side of the tank, obviously the main tank drain, though the draining process is very ssssslllllooooowwwww. I'll try pushing air in through this drain in the next few days to see if I can clear the 'blockage'.
There are also two metal petcocks located on the bottom surface of the tank, not far from the plastic drain. These appear to be pressurized, one flows hot and the other cold. Can someone fill me in on the purpose of these two metal petcocks?
Many thanks in advance.
