In order to reduce my darkroom water consumption I have installed a simple timer on the supply tap to my NOVA print washer.

water timer

By timing how long it takes to first fill the tank, I can work out how long I have to set the gadget for to achieve the desired number of water changes. May be of interest to others. The link is to a UK suppler, but I'm sure this sort of thing is available in most countries.

Dave, I think you should write a product review on just how you use their product.

It would be interesting to see if they leave your review on their site!

Why should they not?

They unit is a simple clockwork valve, roughly calibrated in 15 min sections up to 2 hours. It fits on the water tap and has the wash-tank hose connected to it. I simply turn it to the setting for the wash duration that I want to commence the wash cycle. The unit turns off the water supply after the preset time. I suggest timing the tank fill time so that you can calculate how long to leave the water running for say 6 cycles, or you can let it run for your chosen time. It simple removes the danger of me forgetting to turn the water off.

Hmmmmm, point taken, I just thought as it is a garden supply item they might frown upon the usage, but with reflection, it actually enhances it's selling possibilities.

I've a garden type which shuts off after a pre-set
number of gallons have passed. Haven't seem them
on the market for years. Now days, AFAIK, they are
all timer types. Dan
