Where can I buy this topoff unit?

Here's a pic. I like this unit alot. It is inexpensive and has worked for 7 or 8 years without any problems. No pumps, float valves, or electricity in the water. The clear tube goes in the water. As the water level goes down, changing pressure in the tube closes a diaphram switch opening a solenoid valve. I use a float valve as a secondary safety device so if the valve gets stuck open, the tank doesn't overflow.

Simple and cheap. Unfortunately, I can't find a new one. Anybody know where I can find one?

Well, I found one by Spectrapure about $50 more than I paid.

Thanks ScorpiNO. That's similar. My topoff water is already pressurized so a pump wouldn't work. If there's a solenoid valve available that I can plug into that plug easily, that would work.
