Anybody using header tank float valves

[DocsMapleSyrup]

I'm wanting to incorporate a stainless steel dual float valve switch into my header tank so I don't keep overflowing my header tank because I'm talking to much and forget to check how full it is. I'm wondering if people have used a dual ball float valve to keep the head tank full without over flowing the tank? Thanks.

Guilty of overflowing head tank myself. I put T in lower feed line from head tank and ran clear 3/4 inch milk line back up into head tank. This gives me a visible sight reference to level in galvanized head tank 7 ft over my head.
Not fool proof by any means but has cut down on the spills.

We do. We are using a reverse sump float. Works great once it is dialed in.

High and low level floats are pretty common.

A couple of relays can be used in conjunction with the floats, but probably the easiest set-up is this:

The circuit board can be found here:

I like what you posted. What are you using for a 12 VDC input? Are you using a large 12 V battery or using an AC/DC inverter of some type?

We use a sump pump switch, like white. Just turn it upside down. Very simple, cheap, and you can find a replacement switch if needed in any hardware store. Keep it simple.

Letting my geek side get the best of me, I went a totally different direction to accomplish the same thing, really.

But looking at the circuit board, the 12V is being used only to power the circuit and isn’t required to do any heavy lifting. This means you can get away with a smaller battery if you don’t have AC out in your shack…something on the order of 7 amp hours should keep you in business for 8 to 10 hours between charges. Like this:

Better still, a wall wart if you do have power out there. 12V @ 1 amp would be plenty.

These days, most of us have a box of these things taking up space in a closet somewhere. Find one with the right voltage and current rating. Just cut the jack end off and wire through a fuse (1 amp) to the board. I’d be tempted to put in an ON/OFF switch to keep things neat, but you could always just unplug it.

This will work, but others have offered solutions that may be easier/cheaper to implement.
Choose what’s best for you.

If you don't have the required power you need to run this you can simple put a bulkhead fitting in your head tank at the full mark and run it back to the supply tank. This is what I do for my permeate tank as I over fill that several times. You just need to make sure the return line is about 1 1/2 the size of your supply line. If my 275 gallon permeate tank gets too full it goes outside instead of the sugar house floor. Jeff

Thanks for the ideas and the help guys. I'm going to try the circuit board powered by a wall wart.
