Blimey - I live in the UK and have searched everywhere for a straightforward and sensible explanation of how float switches work - only a good old American company can explain it as well as this. Thank you Bee Cave Drilling !

Your channel is amazing, a lot of us live nowhere near Texas so your help on here is really amazing and it's giving me some great ideas for my home water storage.

I have used these floats for 35 years. They are the industry standard in my area, and they are in my tank at my house.

I think what you have is actually a float valve, rather than a float switch. If that is the case, then you need to adjust the angle of the float valve so that it shuts off earlier. There is also a chance that the valve may have been damaged due to water flow. We call this "washing out" where the water flowing through the valve at a high rate of speed can cut a groove in the seat of the valve. If this happens, you need to replace the valve. The other possibility is that the float and stem combination is not strong enough to overcome the water pressure. You can fix this by reducing the incoming pressure, getting a longer stem, and/or getting a bigger float.

This explanation is good enough.

I've got a different type of float switch. It's a ball floater similar to the type in a toilet tank but made of brass. I noticed yesterday that it's floating too high and letting water overflow out of the tank where the pipe enters. Any resources for how I can adjust the level? It's going to literally be a pain no matter what because I also need to figure out a way to keep the mosquitoes out of it. This is not a system we put in but the float is only a couple months old. I'd like our power bill to go back down! This slight bit of overflow keeps the pump running much more than it should.

Great video, Jim. Very informative, and exactly what I was looking for. One question -- How does the cord of the float switch pass through the tank wall? Do the tanks come with some sort of port for that, or do you have to drill your own and hope it doesn't leak?

Do you include any check valves downstream of the storage tank, with the booster pump? Or just upstream of the storage tank, with the submerged pump?

What kind of maintenance do you have to do on these tanks yearly? Cleaning and such? Also do you have to add any chemicals to keep bacteria and alge from growing? Or will a UV light in line from the well be enough to stop bacteria from forming?

So you really only need two float switches for storage tank? One to keep her from overfilling and to turn the supply back on if it drops much at all and then another switch way down there that will open the circuit if there is not enough water available to pump. The "reserve" deal I don't get? The only thing I can think of is that it would prevent like irrigation left running from draining all my drinking water but then that would be a whole other pump or valve being controlled? Cause as far as my house? I might like an alarm if the tank is getting half full but I don't want the the thing shutting my water off to "reserve" half the tank! What have to go flip a switch to okay using the "reserve"? See my confusion?? Then again you could write whole books on the crap I don't know about this subject ...man i need to learn though! I seriously need to buy and employ a large storage tank for my home! Do they have a specific place in storage tanks for these float set ups? the one video I watched the guy just hung it through the hatch hole at the top...what the hay? What? Cut a slot in the cover for the wire?? I dont get it?

We have a large cistern for our house, we have the water pressure up fairly high due to the increase in feet elevation from the pump to the cistern. We are having trouble finding a float that will shut off the water. Would this type work?

Thank you. I want to control my tank water level so when it is 1/2 empty the pump will start and stop when it is full and the cycles repeat. How does the mechanical switch trigger the electrical to On Off Pump? Would a Non Modullating Float Valve works better and more reliable than a Float Switch?

is the top float switch in water storage tank just for deep well pump to go on and off? mine now turns off the deep well pump when its raised which it should but also turns on the pressure pump at that point to fill pressure tanks. seems like that is wrong did it get wired it wrong. thought the lower float switch was for pressure pump.

How much for a float switch and how do you wire it to the pump? I need to finish my well.

Hi 👋👋how can i do that. .. Installation auto with pressure tank.

Would this float switch work for a Drummond 1 HP shallow well pump?

Is that float switch powered thru the pressure switch??

What happens when the power goes out? I have a system that is automatically fed from the municipality, but sometimes our power goes out for an hour or a day. Will the tank overfill in this case?

Hello, Thank you for sharing this information. Would you recommend the JSE pump master plus float switches for a 1.5 hp Goulds submerged pump?

Thank you sooo much!

If you don't mind, what brand of float switch do you use?

send u float switch contion diagrm

i know how to cnnect ths things
