Drain/ valve locations

I have a 74 center bath 31 sovereign. I have found three valves. One at back by city supply, and two under the floor under the oven. Of the latter 2 I know one is a drain and I'm thinking the other is the cold. Am I missing another valve or have I found them all. I have notes from previous owner talking about another but he has passed so I can't ask for his wisdom. Thanks.

You're asking about drains for the fresh water system, right? Typically, there are 3 of them. One drains the fresh water tank, and then two low point drains to drain the hot and cold water lines. Try looking under the trailer for water lines that stick out the bottom. There should be a drain valve for each one inside the trailer.

If you have a roof a/c, there will be an extra drain line directly in front of or directly behind one of the wheel wells for it. This is typically a vinyl tube, and it'll look different than your water line drains, which may still be be copper, unless a PO replaced them. You also may find a drain for your fridge, but again, that will be a vinyl tube that will look different from the water drains.

There should be another low point drain valve in the rear of the trailer check in closet, near Univolt, and in rear compartment.

Found mine today. Just to the inside of the fresh water tank drain. Winged petcock valves protruding through the belly pan. I presume that one is for cold and the other for the hot lines. At least they are not plastic.
