Air in water lines

[CPCole]

Hey all so in de winterizing my 2013 Starcraft Autumn Ridge 336RESA I got all the anti freeze out and the water was eunning great until I filled the HW tank then I got all kinds of air and sputtering in the faucets. The water did get hot eventually but it was very loud burping when the water was running. Shoulr I prime the pump even though I shouldn't need to? Looking for advicde since this trailer is new to me. Thanks in advance.

It takes a while to fill the tank, and there usually is a bit of trapped air, that has to work its way out.

When I fill my water heater, I open the pressure relief valve. This appears to purge more of the trapped air at the top of the tank, than just running a faucets.

As for the pump, there is no difference in getting the trapped air out than being connected to city water.

Fyi, never run you heating elements unless there is sufficient enough water in the tank, or it will overheat and fail.

as stated, you must release the PRV to get the air out of the WH.

When my water heater is filling, I just open the nearest hot side faucet to purge the air from the water heater. Keep it open till the water runs steadily.

Quite normal behavior as you remove the air from all the lines and the tank.

I like Jagiven's idea of filling the hot water tank by opening the hot water tank pressure relief valve. Not mandatory, but would cut down on the amount of air pushed out of the tank and into the hot water lines as the hot water tank fills.

Main reason I do it this way. I never have full hookups, and I don't want to fill my waste tanks prematurely.

That's a great point! Honestly never considered that.

Are you saying you can do that while you are filling the primary water tank? Will it draw into the HW tank without having a hot water faucet open?

I turn on my pump, and open the pressure relief valve. When the tank is full it's i close the valve and turn off the tabk.
