Solenoid valves - water drain issues

Good morning everyone! This is a great site with a wealth of information... I hope to contribute as much as I can take from it!

I have recently acquired a 1989 Country Coach Concept. It's pretty amazing as it's my first RV ever! I have a ton of stuff to learn though.

I've done a lot of searching on the site but it seems like most people have manual valves when it comes to their water tanks and systems.
Mine are Goyen 12V dc solenoid valves. Model 12BWJ2

They are normally "closed" (stopping the water from emptying) and "open" when I flip the Water Drain switch. The thing is... they don't seem to fully close if at all. The only way I can keep water in the tank is by sticking a cork in the drain tubes below the valves.

Can anyone supply ideas on where I can find proper repair kits? I've cleaned the valves (coil and diaphragms) and they still don't work right. I think they're old and tired. I'd LOVE to not have to replumb in NEW valves.

Thanks for reading!

here is a link to a supplier of valve repair kits for your valve. Normal operation of these valves as far as maintainance is to use them monthly. You may have some debris around the sealing surfaces or a weak return spring. Attach to city water or use pump to pressure up the system. turn on drain switch and let water drain. Cycle a few times. see if this helps. if not you can order the repair kits. I had the same problem with my electic toilet. Small debris and a weak return spring. Stretched the spring and cleaned the rubber; now shuts completely. let us know how you make out.

Thanks for the tips.. I got the replacement kits now (ordered 2) and installed yesterday.. As I still need to wire in the new pump I have not yet tried these valves. I really hope they work good now!

Wish me luck!
