How low can I lower tank pressure with this switch?

you know I didn't have to do anything to it but it dos'e turn off a little high but was alright. My point being the old switch had two screws on the top of the contact area one for high end turn off and one for low kick in. The new switch, I didn't notice if it had adjustment screws or not but it should. Instructions for adjustment should be under the cap.

Sorry, I don't know the pressure. I use mine on a Coleman light tower and it works great. The tank is located below the engine and has no problems

Maybe your pump capacity is too high for your application! Without knowing the volume you are trying to remove in a given period of time it would be hard to answer your question. This switch is designed to operate on just a few inches differential.

What size is your pressure tank? That could be part of the problem, smaller tanks sometimes fill quickly and cycle on and off more than larger tanks. Also usually the pressure switch is set for a 20psi differential not 30psi. You also may have a leak in the tank or the "empty"pressure is not set right. To set that empty the system and set the pressure 2psi less than the start up pressure. Hope some of this helps

That is pretty low for a high pressure cutoff. Numerous youtube videos describe how to adjust pressures on these. Turning the nut with the small spring counterclockwise should reduce high pressure cutoff, but you'll need to also adust the nut with the large spring to change the range so that the unit will still turn on at a lower cut in pressure. Probably someone will have a more definitive answer.

I'm not sure if this is what you mean but I put it on my low water pump. It puts air pressure in the holding tank.

Should be no problem if you have a pressure tank after the RO. Order the 60 or 80 psi pressure switch if the tank and RO can handle it.

I'm using it on a 55. That reads nearly 2000 psi on the tank side, and is adjustable on the output side. I'll note that if you need it to be a pressure under 50psi on the output, it may take a little adjusting to get just right.

High and low pressure settings come pre set from the factory for a given range such as 20/40 or 40/60. That being said either of these pre set pressures can be adjusted by use of 2 pressure adjustment spring loaded screws. There is a limit to the adjustment so you should purchase a switch that is pre-set closest to the pressures needed or wanted for your system. Remember if your system has a bladder type expansion tank the air pressure will need to be reset in the bladder if you change the low pressure setting on your pressure switch. I hope this is beneficial.

they don't seem to take a lot of pressure, I set mine on very low and they work fine.

if the switch is a pump-up type,it will shut off when tank is full.A pump-down switch does the opposite.

You would need to buy a separate 12v dump valve. For the switch use a momentary toggle on/off/on

According to the manual with my #61800 you can select 30, 45, 60, or 80 psi. Selector is inside tank.

Depends on how low. My pressure is pretty low as well about 40-45 psi and still works great!

It's all determined by what type of pressure switch you have and how many pounds of pressure are in the tank. If the tank pressure is set too high or low it's going to effect how much water is supplied. Different pressure switches like 20-40, 30-50. 40-60 are going to require different pressure levels inside the tank. Those should be set before the tank is filled with water. It's difficult to say when the pump should come on without knowing what type of switch you have, where it's set, and how much pressure you have put in the tank before installation. Incorrect setup can badly effect water supply and pump function. It's all determined by what type of pressure switch you have and how many pounds of pressure are in the tank.

This pressure switch it basically designed for a 2 stage compressor. My cut in pressure is 160 and cutout is 175. I don't know if the cutout can be set down to 135 or not. the description says it can be set as low as 70psi. 5 hp motor is going to be getting close to its rated amperage, so make sure you check the amperage ratings on your motor. Some 5 hp motors take a lot more to start than others.

this is not a good choice if you put the pump 200 feet down, as the pump will stall (zero flow) at 221 feet of head.Subtract your setting depth from the 'shutoff head', and multiply the difference by 0.433 to get the maximum pressure at the tank.Set your cutoff switch somewhat below that max pressure or the pump will run continuously....
