IlliniCathy Posted July 29, 2021 Share Posted July 29, 2021 (edited) We have a 2002 Knight, we have not found the overflow for the fresh water tank. It seems that the tank must be full, but the water just keeps going in without coming out anywhere on the ground or on the inside. Can you guys help us out? This is a new motorhome to us and we sure love it. Thanks all. Edited July 29, 2021 by IlliniCathy Typo Link to comment Share on other sites More sharing options...

Are you certain that your ( filling the tank ) Run a faucet and see if you have pressure or not as you fill. You should NOT Link to comment Share on other sites More sharing options...
Gary 05 AMB DST Posted July 29, 2021 Share Posted July 29, 2021 Cathy, on my 05 Ambassador, the rear of the tank is higher than the front. From the front, the water level is even with the top of the tank but if you open the access panel on the passenger side you will see the water is about 2" below the top.

redstickbill Posted July 29, 2021 Share Posted July 29, 2021 Cathy, I am not familiar with your coach. At times when I got "too" busy trying to get underway and filling the fresh water tank on our 2004 Endeavor, it would overflow and show me where the overflows were under the coach. Other than a wet mess it should not hurt anything. Bill B 07 Dynasty Link to comment Share on other sites More sharing options...
Dr4Film Posted July 29, 2021 Share Posted July 29, 2021 Our fresh water tank overflow is on the passenger side just in front of the rear dual wheels. You can see the overflow tube when you open the tank bay door which is secured with screws underneath. The tube forms a U shape from the top of the tank going up then over to the edge and finally down through the bottom of the floor. The shape prevents the overflow tube from siphoning the water from the tank. 1 Link to comment Share on other sites More sharing options...
Bob Wightman Posted July 29, 2021 Share Posted July 29, 2021 On my 2004 Knight we have two fresh water fill ports, one where you screw a hose on to the the panel and open the valve to fill the tank, the other is where you take the cap off to fill the tank by sticking the hose in. In either way of filling when the tank is full it overflows out of the port where you stick the hose in to fill. I normally remove the cap on that port when filling to let the air escape more easily. 0FE4718D-3922-4F51-A863-F400BF681A3E.heic Link to comment Share on other sites More sharing options...
Dr4Film Posted July 29, 2021 Share Posted July 29, 2021 Bob, Unless Monaco totally neglected to install an overflow tube in the Knight coaches when they were built which seems highly unlikely it is possible that your overflow tube is blocked with Mud Daubers.

ncsteve Posted July 29, 2021 Share Posted July 29, 2021 On my 04 Knight, the overflow is opposite the fill ports on curb side and exits in front of rear wheels. I fill mine through the screw on hose fill until is starts running out. Link to comment Share on other sites More sharing options...
Bob Wightman Posted July 29, 2021 Share Posted July 29, 2021 ncsteve and Dr4Film thank you for posting! I also am a new owner to an older coach and did not know that overflow was there. I just crawled under it and found it on the wall in front of the passenger side rear wheel (never saw it before). It has some sort of rubber nipple sorta thing on there to (I assume) try to keep Mud Dobbers out. I'll pull it apart over the weekend and clear the blockage. Thanks guys for the help, and thanks illiniCathy for posting a question about a problem i have that I didn't even know I had. Link to comment Share on other sites More sharing options...
wa6e Posted July 29, 2021 Share Posted July 29, 2021 Like Dr4Film, my 2007 Cayman overflow tube is in the passenger side wheel well in front of the tires. Gerry 07 Cayman Link to comment Share on other sites More sharing options...
