All I iwant is the low pressure cutoff to protect a water heater. Can I adjust the high cutofff really high?

Depends how high. These switches usually maintain a differential of 20 - 30 psi. ie Low cut out 30, High cut out 50psi. I'v had mine set to cut out at 70psi if that's any help. I did reduce it to the 30 -50 range as in the summer here it easy to blow the pvc pipe. I think max for a water heater is 70psi.

The low pressure cut-off is to protect your water pump if/when the well runs out of water. In other words, if this pressure switch sees 0 psi, it will turn the pump off so it is not running dry. If this happens, you will have to manually reset it.

The best way to find out is to try it. It's purely mechanical, and the adjustments are not completely independent. Make sure you get a model of this product that has the low-pressure cutout. It's a new addition. Also buy a model with the highest pressure range you can find. There may be differences other than adjustment among those models. I like your idea.

The switch comes precalibrated for most tanks. the very first thing that you should do BEFORE replacing the switch (unless you are replacing it due to the contacts being worn out) is to COMPLETELY empty the water out of the tank, then make sure that the air in the tank (bladder, there should be an air valve like on a bicycle tire on top) is correct, if not inflate it to the specifications fro the tank, there should be a label with the air pressure settings , usually about 28 PSI or so. make sure the power is OFF, check it with a voltmeter to be sure! replace the switch. Once this is done, you can fill up the tank again and see where it cuts off and adjust if you want the preasure higher or lower. then open a water valve and see where it cuts off and adjust so that the switch cuts off at your desire setting, if the pump starts to "flutter" on and off real fast, the pressure in the tank is not correct or the low pressure is to close to the cut-off setting, lower or raise the small screw accordingly. this is what the instructions say for the bolt settings if you need to adjust it : "Turn the nut on the small bolt down (clockwise) for a higher cut-out pressure. Do the opposite for a lower maximum water pressure setting. Remember that you're not directly setting this pressure; rather, you're establishing how high you want the cut-out pressure to be above the cut-in pressure." hope this helps. and definitely test as indicated in the first answer! as this cause grief for me several times during the summer as ants...yes ants looked for cooler shelter and started to "burn up" on the contact, using a nail filler i was able to repair it for several years until there was no contact left, spraying some WD-40 below the housing helps as ants will not go onto it and it lasts longer than ant spray. : )

You definitely want to be able to adjust the working pressure, as different diffusers and reactors require varying pressures. I got tow of these through Amazon, both of which were defective and had to be returned. Wound up buying a custom unit from GLA. Maybe you'll have better luck with the Aquatek.

it can be adjusted but max pressure would be 850 psi. you should look into a SHP regulator made by ninja that will have the high pressure you want.

I don't see an high low pressure settings. It looks just like the picture. All the function keys are in the front. U can choose rice, beans, pork, beef and the pot just set the time and the pressure for u, you don't have to do anything.

This pressure switch is pre-set at 30-50 psi. If the cut-off or cut-on pressure needs to be changed, turn the larger spring nut clockwise to increase the cut-off and cut-on pressure. The rate of increase is 2 1/2 PSI for every complete turn of the nut. This adjustments maintain a 20 PSI differential between cut-on and cut-off pressures, which is best for pressure tank performance. Do not adjust the small spring which changes the cut-off pressure (to raise, turn clockwise). Never adjust cut-on below 20 psi or cut-off above 60 psi.

This switch is adjustable. You can set the cut-in and cut-out pressures separately. It's set at the factory for 40/60, but you can make adjustments internally to lower (and I think higher) pressures, e.g., 30/50. (Note: I haven't done this and I don't work for the company and accept no liability.) The Square D web site is not very helpful, but the web site for Pumptrol (the Square D pressure switch brand) has a lot of info. If you look up the 9013 series of pressure switches, you'll probably find the info you're looking for.

Yes you can I am assuming that your water lines are cpvc and have the appropriate heat rating. You can find the rating printed on the pipe itself. The water heater will only heat to 140. You can bump that to 160 but need to install the commercial controller. Hope this helps.

The line that says min. water level is actually the max. water level. Do not completely submerge the heater.it can drop an inch or two below that line and should be OK. It will not shut off automatically

I would suggest this is a question for the manufacturer. I use mine for a water heater.

There is an adjustment to regulate the water to avoid scalding. The plumber told me he could remove it or adjust it. I had him remove ours since we do not keep our water heater too hot anyway. It works fine now.

Yes, remove the hi pressure gauge and put a 1" or 2" extension pipe where the gauge was. Make sure that the threds on the extension are going the right way. They will be left or right. Than add the second regulator to the end of the extension.

Close enough, though the default pressure is set lower. Should adjust to 40-60 without a problem. Not sure why Square D has scores of different part numbers for these switches with barely any detectable difference between them. Good switches, however. They work for decades.

This rough-in valve body doesn't regulate. The Delta faucet cartridge you put in it does. The cartridge will comes preset at an anti-scald level. You can adjust the action to allow more hot water, up to the temp of your water heater. Instruction on how to make this adjustment comes with faucet cartridges. http://www.deltafaucet.com/media/MandI/68881%20Rev%20E.pdf It's explained here in adjusting rotational limit stop.

There is no adjustment -the heater is automatically "on" when the water is being circulated. Works very well in keeping the water temperature about right. If water temp gets too high for comfort-not our experience- you can just shut off the circulating pump.

No problem. Just do not allow the water to boil off completely. I use a programable thermostat to shut the heater off or hold at a desired temperature.

Haven't had a need to go that low. It is adjustable and I have increased the max from 35 to 50 PSI. Suggest you contact the manufacturer.
