How to hook a 110v motor to a 230v pressure switch?

[grantiman]

I have a well system with a chlorinator in the line. My chlorinator pump is wired into my pressure switch. I have a 230v power line going to the two end screws on the pressure switch, and my well pump going to the center lugs. My chlorinator pump is also wired to the center lugs. My problem is, I have a new chlorinator pump, this pump is 110v, I needed a 230v. I cut the end off the cord to wire it in before I realized I needed a 230v pump, store wouldn't take the pump back because of the cut cord. What I need to do is wire this 110v motor to my pressure switch which is wired 230v, can It be done? If I connect the blk wire from the new pump to the pressure switch (on the well pump side) and run the new pumps common wire back to the panel box, will this give me the 110v I need? I've done wiring before, so if something has to be changed to get this new pump to work, I can do it.

If you have a neutral in the pressure then you can connect between one of the switched hots to the neutral for your clorinator. If there is no neutral you can replace the cable to the pressure switch from the panel a cable with a neutral.

Hi grantiman ,
- it's possible but not advisable to run the hot line of the chl. pump to one of the switched terminals on the P/S. As you say, run the neutral only to a nearby socket or panel. :cool:

Do it Right - Do it once.

Yes, I connected my hot wire on the chl pump motor to the hot well pump terminal in the p/s and connected my ground. I then ran a new common wire from the panel box to the p/s and tied my common from the chl pump to that. The chl pump runs fine, turns on and off with the well pump. I know it would have been better connecting 230v to 230v, but by wiring this 110 motor to the 230 p/s the way I did, this isn't going to hurt the new chl motor or cause anything to over heat is it?

You are not going to hurt the clor. motor. However you must run that new white wire in a conduit with the other wires tothe switch. You are not permitted just run a single wire in free air or taped to the side of the old cable.

yes, I did run it through conduit most of the way. I didn't use just a single wire, I use 14/2 and just used the white for my common. I think I may just replace the whole line with 3 wire and just use the extra wire for my common. Thanks for all the help.
