2013 QBB trailer - No hot water cannot find valve under sink
« on: November 30, 2020, 01:35:37 PM »
Hi,

Can someone give advice on where the hot water valve is - I cannot find it. Blue/red tubes under sink, then to compartment below, then they go to the left outside, no valve anywhere.

I have cold water, but somewhere the valve to hot is shut off.

thanks very much, I'm done crawling on the floor for the moment!

The valves you are looking for should be by the heater to turn the hot water on for the trailer. Should be under your bed in the front left corner of the trailer. Should have 3 valves, 1 going into the heater, 1 leaving the heater, and 1 joining the in and out lines.

Valve going into the water heater needs to be "on" - valve in parallel with the water line.
Valve coming out of the water heater needs to be "on" - valve in parallel with the water line.
Valve joining the "in" and "out" water lines needs to be "off" - valve perpendicular with the water line. This is the bypass valve for winterization so antifreeze does not go into the water heater. You would shut the other two valves off and open this valve up to isolate the water heater.
