Does your overboard drain have a shut off valve on it?

CW said they checked everything on their receiving inspection ! BS . The problem with the pump and drain was that the valve for draining the tank was half open thus keeping the pump on to maintain pressure . Lessons learned !

I have a 29.3 and said valve was under outside sink .

The tank drain is separate from the pump and shouldn't have any drainage with the pump on. The drain is just a hole in the bottom of the tank with a valve attached. If the pump is on, drain closed, and you're still getting water under the coach you have a leak somewhere. Open all your basement doors, turn the pump on and start inspecting with a flashlight, the water could be coming from anywhere there is a fitting or joint.

I should have said that I closed 2 valves . When I hooked up city water I had a leak as well which stopped when valve was closed .

Most of these Thor products now have the drain line as well as the vent line plumbed out the bottom of the coach. The drain should have came with a valve installed from the factory, the vent is/was installed without a valve. The problem has been the vent line, once the tank is filled the vent begins to siphon & continues til the water drops below the line. The factory has added piping to some & created a loop in that vent line, others have just added a valve to it, which is what I've done, but you must remember to open the vent valve when filling so as not to rupture the tank. The vent was designed to be attached to the small screened port next to the fresh water fill opening, but in their infinite wisdom thought it made too much mess when the tank was full & ran out that small port, you could plumb it where it belongs also.
