manholt Report post Posted September 25, 2014 I have the shrink plastic pipes for all plumbing. The valve that allows me to change from city to coach water tank has failed and I'm on city only. I have tried all the usual places to find a replacement ... none! AMC parts dept. none. I even had the pre-rally tech's look at it...no help! Now, my vice grips don't even work anymore...HELP! I'm in Galax, VA. Tomorrow, I'll be in Roanoke Rapids, N.C., for a week.Carl C. Share this post Link to post Share on other sites
jlandon13399 Report post Posted September 25, 2014 You probably have a three way ball valve to select city or to fill your fresh water tank. It should be brass or stainless steel. Try a hydraulics or pneumatics distributor to see if they have a replacement valve. Share this post Link to post Share on other sites
kaypsmith Report post Posted September 25, 2014 If you do get a 3 way valve, try to replace with stainless steel if possible. Stainless is more forgiving during cold weather conditions. Share this post Link to post Share on other sites
dickandlois Report post Posted September 25, 2014 Carl, Could you post a picture of your valve for the group? Then we would know how the valve is plumbed.Rich. Share this post Link to post Share on other sites
manholt Report post Posted September 25, 2014 Thanks to all. It's not a 3 way or inline, has nothing to do with filling coach water tank. This is a L or elbow with a ball valve, does not have treads on either end, heat shrink, 1/2"...it's only function is to send water from city to inside of coach or from water tank via water pump to coach!

wolfe10 Report post Posted September 25, 2014 Cut it out and install a new ball valve. Check out shark bite and other easy to install fittings. Share this post Link to post Share on other sites
kaypsmith Report post Posted September 25, 2014 The type valve that Brett mentioned can be found at Lowes, Home Depot, and other hardware stores in the Pex plumbing accessories. Share this post Link to post Share on other sites
manholt Report post Posted September 25, 2014 Thank you! I will head back to Lowes tomorrow...I forgot about Pex. The young Customer Service plumbing rep. told me they had nothing to fix my problem...I did not want to possibly prove him wrong. He had no legs, I saluted him and left! Carl C.

elkhartjim Report post Posted September 25, 2014 Remember you will also need the clamping tool for the Pex fitting. Share this post Link to post Share on other sites
kaypsmith Report post Posted September 26, 2014 If using shark bite, or gator bite, or whatever name they are called, depending on where you get them, these are push on fittings that do not require a crimping tool. Just remember to carefully debur the outside of the pipe. there is an o-ring that makes the seal, and if you snag that ring, it will leak. Share this post Link to post Share on other sites
kaypsmith Report post Posted September 26, 2014 If you are plumbing savvy, two inline check valves can be used to eliminate the need for manual valve. Place the first one immediately after the city water entrance, the second one between the pump outlet and the entrance to the main water plumbing where it enters the pipe. This system works well, especially if there is an accumulator in your system, if there is not one, can be added very easily. No more having to use a manual valve.

manholt Report post Posted September 26, 2014 I think my coach was built on a "hung over" Monday! My city water connection is in utility compartment, along with the aforementioned fresh water tank/city water switch. My other 2 way "on/off" or "fill/bypass" valve for city water to Coach fresh water tank is in the sewage macerator compartment. You can also fill fresh water tank from the outside with a hose! You can't get fresh water into coach system, unless it's city water pressure or in-house pump, that's normal. What's not normal to me, is a on/off elbow ball switch! I will be back on Island in 10 days (keep coach in Dickenson)...I'll be happy to show you, Brett. Share this post Link to post Share on other sites
