Air Flow Problem While Winterizing

Hi,

I tried to post this in the "Winterizing" subforum, but for some reason I'm not approved to post there. So here is where I wound up.

I've winterized a series of Jayco fivers using air pressure over the years. No problem. But this is the first time I've tried a Silverback (2014 33RL).

I drained everything, bypassed the water heater, attached my air hose adapter to the fresh water intake fitting, attached the compressor, and nothing happened. No water or air at all coming out of the first thing I try -- the utility water hose right there in the compartment. So I go inside and sequentially try every faucet and the toilet -- no hissing, no spurting of water. Nothing happening.

Went back outside, disconnected the adapter from the fresh water intake, and checked to be sure there was air coming out of the hose and through the adapter. There was. Reinstalled it, and still no expected results. No sound at all of air hissing from any of the water outlets, and of course no movement of water. Switched the water valve on the panel from the on-board water setting to external source setting -- still nothing.

So I'm stalled out and puzzled. It's a nearly stock system, other than removal of the water filter (straight Pex in its place), and installation of a small accumulator next to the pump. Is there a check valve somewhere in the system that is keeping the compressed air (30 psi) from moving past it or the water pump and into the rest of the water system? Have I forgotten some important step in the process? Is the Cedar Creek system so different from Jayco's that I'm doing it completely wrong?

I would appreciate it if someone could help me figure out what I did that I shouldn't have done, or what I didn't do that I should have done. (grin).

Thanks.

Rich Phillips

There's a check valve right at the inlet.
It's either stuck or 30 psi won't overcome the spring pressure.

Can't imagine you did anything wrong. Sounds good to me.
As TURBS said the check valve is right where you connect the city water hose. (or blow-out plug) I surely would think 30 psi would overcome the spring pressure (inlet side) but maybe not. Bump your pressure up and see if it works.

Which fresh water intake? Outside or do you have a hose like shown in the photo? If you are using a system like shown make sure you have switched the valve. If you don't your system is still connected to the fw tank, not the hose.

Hi Oldtool,

I have two female garden hose type fittings in the vertical panel that has all my various controls.

One is very clearly marked for the black water flush. The other is for connecting to shore water. It is the one I am using for air injection.

Gonna try to get over again in a little while and bump up the pressure, as suggested.

This is not a mission-critical project. I do my pink stuff first, and then push it all out with air. Yeah, it's sort of "belt and suspenders". But by having the antifreeze out already in the spring, it is that much faster to get usable water on my first warm weather trip.

Thanks for the tips, everyone.

OK, so you are using your fresh water connection. It sounds like the check valve on your fw pump may be stuck. This would mean you are trying to fill your fw tank with air, and that would take forever. That would act as if you were hooked up to the fill port for your fw tank. The purpose of the check valve is to hold pressure in your system when using the tank and pump, but it also keep the tank from filling when you are hooked up to city water.

Fixed!!

Hi,

Well 60 psi did the trick to get things going. I then was able to throttle back to my usual 30 psi, which maintained a nice sputtering flow at all faucets until the pink was out.

Thanks for the advice, everyone.

Air

The fitting goes to city water connection not fresh water
