Thinking of adding a speed control knob to sink pump. Thoughts?

[OldSpice]

I don’t *think* I’ll run into any problems but thought I’d post here before I do in-case I’m missing something. I think I heard the sureflow faucet has adjustable flow or am I making that up?

I think my pump is on its way out anyways, I had to give it a vinegar bath and smack it to get it pumping again. can anyone recommend a good backup pump?

Current goal = 1. speed adjust knob to adjust water flow- + 2. foot button with separate on off switch to allow foot activation without accidental activation. 3. Maybe a new faucet for better articulation.

Our Shure flow does regulate the flow on our 82. It has a submersible pump and I have deleted the city water connection. That was an accident waiting to happen. Plus it's one last thing to put away every morning when you hit the road.

Do you know if it regulates flow via physical construction or if it slows down the motor via voltage?

Yea I’m wanting to get rid of the water connections outside van but not sure what I should replace the boxes with- maybe a 12volt plug in for hooking up air compressors etc outside van.

It's purely a flow restriction. Works just fine.

Don't know that answer. Likely flow restriction vs lower voltage. It is light years ahead of the original.

The Shurflo faucet commonly used to upgrade a Westfalia galley faucet has a binary switch attached to the valve for turning on/off the galley water pump. There is no rheostat to provide variable control voltage.

Any control of the water flow is done simply by the Shurflo's design as a valve; you can open the valve more to get more water (as much as the pump will deliver), or you can close the valve down to restrict flow and decrease the flow of water (but the pump is still working just as hard).

Water pressure varies from site to site, and if there was a leak during the night, the van would be full of water by morning. We have found the 12 volt pump and on board tank to be plenty for us. We fill it to the top of the yellow and we are good for a few days. Don't like to carry extra weight either.

I will get to the question but first. We have the foot controlled switch arrangement sold by GoWe$ty and the Shurflo faucet, after adding a pressure bleed it has worked flawlessly.
But, a PWM controller coupled with a foot pressure controlled transducer would be the cats pajamas. Press lightly, low flow, press harder and more flow. All to replace 2 cents worth of copper strips.
Now to devise a 3 quart hot water heater that takes up zero space.

You can control the flow with a .5 gallon aerator
