Why does my RV not have hot water pressure?
If there is no hot water at all, first check to see if the bypass valve has been turned off. You may have forgotten to turn the bypass valve on. Go outside and look for a lever or valve labeled Water Heater Bypass. If you find your RV has one, switch it off the water heater bypass setting.
What to do if your RV has no hot water pressure?
Cold water goes in the bottom and hot comes out the top. If you remove the valve (or valves) and find it’s full of calcium deposits, I suggest you buy a new check valve from a local RV store. You can remove it completely if you’d like as it only prevents back pressure and replace with a 1/2″ by 2″ coupler from any hardware store.
Why is there no pressure on my hot water heater?
I drained and flushed out the hot water heater a couple of times with some calcium deposits flushed out. Still no pressure or water flow from the hot side. Heater seems to work fine but no water pressure. The hot water outlet on the rear of the tank seems to be unreachable in the compartment. I’m at a loss. Thank you.
What causes a hot water valve to stop working?
Debris blockage or scale clogging at an individual water control valve where a clump of debris or mineral debris can partly block the valve opening Clogged hot water valve cartridge: some hot water control valves such as at sinks, tubs, showers, use a replaceable internal valve cartridge that actually starts and stops water flow through the valve.
What kind of water heater does not store hot water?
Tankless or Demand or “Instant” water heaters may be electric, gas, or possibly even oil-fired devices that do not store any volume of hot water. When you turn on hot water at the tap, water flowing through the system activates a control to turn on the heater that in turn heats water as it passes through the device.

Why is no water coming out of my hot water faucet?
A faulty check valve at the hot outlet could also reduce, minimize or prevent adequate pressure and flow from reaching the hot faucets. Some water heaters have a check valve located at the cold water inlet to the heater, but since you’re able to fill the heater and see it draining, a check valve at this location is probably still viable.
