Fresh Water Tank Drip
« on: June 13, 2018, 07:21:29 PM »
Our fresh tank developed a very slow drip from the drain valve after sitting for a few winter months in PA. It has the Auto-Drain "feature" (electric valve). Is there an easy way to remedy this? I can access the Auto-Drain but getting to the actual valve mechanism looks ugly. I did see where some have used vegetable oil in the grey/black tanks to lube the valves but not sure if that is applicable to  fresh water or if it will remedy a drip. Any ideas?
Thx, Steve

Steve, can you glue a threaded PVC fitting after electric valve, or on the end of pipe. Then you could use a threaded plug or cap on end of drain. Another possibility is a valve like this, https://www.usplastic.com/catalog/item.aspx?itemid=23307&catid=584 If clearance issues are a problem then a simple plug or cap with old valve left in place may be a solution. Hope this helps.

Frank,
Thanks for the thoughts. The valve is between the rear of the fresh tank and the rear of the Aqua Hot. Only way to access it is to remove an adjacent bay panel. Due to the location, the electric valve is about the only way to easily drain the tank.

Steve, had this problem with ours. Turned out the electric valve mount was loose. Tightened it up and problem solved. Hope yours is as simple. Access is a problem, but since we have the slide-out bed in that compartment, it is a bit easier.

Steve, With my 06 PT is has a 2" velvac gate valve with a electric actuator on it. I can get at it from the underside once I remove the protection can. Four bolts just like most velvac valves. But knowing how things go they changed to a new improved model or and Ford said a better idea. lol

Don,
Thanks for the tip. Mine was slightly loose so maybe that's it. Will add water to the tank later this month and check.
Lee,
It isn't a velvac valve and access from below is not possible as there is a 90 elbow between opening in coach undercarriage "floor" and actual valve. Great idea if it never fails but...
Will let you know if tightening remedied drip.

Ours has an almost imperceptible leak. Solved it with a 2" (or 1 ½", can't remember) plug. If I need to drain, just reach under and remove plug
