Adding Ball Valve to 2008 Fleetwood Terra Heater Line - Safe?
I turned off my RV's cooling system and grabbed my wrench — ready to install a ball valve on my 2008 Fleetwood Terra's heater line but need safety confirmation first. I've been battling what I suspect is a faulty electric heater valve that may not be closing completely when I switch to A/C mode.
The electric valve is expensive to replace and located in an incredibly awkward spot that's driving me crazy to access. I've tried everything - heat detectors, feeling around the lines, you name it - but I still can't definitively tell if it's actually sealing off hot coolant flow when the A/C is running.
Here's my question: Can I safely install a simple manual ball valve in the heater line before the existing electric valve? I'm hoping this would let me manually shut off coolant flow to the heater core when using A/C, essentially doing the job the electric valve should be doing. Will this cause any problems with the cooling system or damage anything? I just need to know if this is a safe solution before I start cutting into lines. …more
