Water heater bypass Serrano

Is there a Serrano 31V owner out there that can tell me were the water heater bypass valve is located?

Thanks much!

I finally found mine under the bed, but here's a clue -- it's probably on the back side of the water heater. Start from the outside water heater access door and measure from a window edge to see where that ends up being on the inside.

It's probably under a bed or you might have to pull a drawer out and look under it.

Good luck!

It is under the sink. There is a plywood panel (angle shaped) that has to be unscrewed and removed. You will be staring at the back of the water heater and there are three valves. Close the two outer ones as they control the input/output from the water heater. Open the middle one as that enables the bypass.

Thanks CoSerrano,

That's were I found them in the end.

I added some shelves in the area under the sink to make it more useful. In the end I created a small door in that plywood panel to access the valves. Works pretty good.

I've added and changed a number of items throughout the unit which makes the unit definetly more comfortable and practical for our use.

Overall we are quite happy with our 31V.
