Thanks for responding mptjelgin.
I’ve been urged by other SKPs to try the forum for help. I’m surprised at such a prompt response Thank you
I’m going to recheck those things, since you asked specifically, and report back.
Assuming it’s a prime problem, what’s the procedure for reestablishing that pressure?
I'm not sure I understand this statement. Exterior valve stem mounted TPMS sensors will send a signal providing the psi and ambient temperature from each tire to the monitor. While it is true that tires in direct sunlight on one side of an RV may read slightly higher than tires on the shady side, they certainly are not limiting the ability of the sensor to detect temperatures accurately.
Surely you are not talking about tires on dual wheel applications. Sensors for both of those side-by-side tires would be mounted/visible on the outside rim.
Sometimes the water pump will lose it's prime and the result is that it runs constantly without actually pumping anything. If you turn the switch on and open a faucet (without being hooked up to "city water") do you get any water out of that faucet? That is, does the water pump actually pump water when you need it?
And are you certain that you've got water in your fresh water tank to actually pump?
