wvujazzman Report post Posted October 27, 2018 Hi Folks, Went out to my coach to winterize it today, and the water pump isn't pulling the antifreeze through the siphon hose. I have the low point valves closed, the normal supply valve closed, and the siphon hose valve open. I've removed the whole house water filter and even filled that container with antifreeze. Hot water heater is drained in bypass mode. In short, I've followed all the Newmar directions and I think I've done everything correctly, but no AF in the system. About the only thing I can think of is that I've got a bad siphon valve, so I'll try to replace that tomorrow. Any other ideas? The water pump is brand new and was working with water 15 mins before trying with AF. I'm stumped... any help would be appreciated. Thanks in advance!

I installed a longer hose to use to pull antifreeze into the pump, and then raise the gallon jug a few feet above the level of the pump. Also helps if there is a faucet fully open so that it's not fighting against the pressure inside. Share this post Link to post Share on other sites
wvujazzman Report post Posted October 27, 2018 Thanks Richard... I have about 3 feet of hose, but it would be pretty simple to install a longer siphon. I did have a faucet open, but I'll try raising the jug as well - didn't think about that. Share this post Link to post Share on other sites
bm02tj Report post Posted October 27, 2018 most pumps do not have alot of lift so you could raise the hose and pour some in to prime pump then keep jug as high as you can Share this post Link to post Share on other sites
mailman Report post Posted October 27, 2018 Eric It has happen to me in the past, 50 plus years of camping. But , if you load the siphon tube with fluid and cycle the pump you will prime pump , top off siphon tube put in bottle, problem is solved. I have added a longer tube to add volume for the siphon tube, for prime. Yes the jug should be higher than the pump.
