I'm currently getting things together to replace the components of our aging home water well treatment system, which consists of, in order from the inlet at the house to the end of treatment:

- Pressure switch
- Pressure tank
- Liquid chlorination injection (tank of mixed chlorine and a pump that activates whenever the well switches on)
- Contact tank
- Activated carbon filter

Our water is pretty good quality, but has some iron bacteria in it, and with the system that was in place when we bought the house, the water has been great from the tap.  All of the components are just aging and wearing out.

I've already replaced the chlorinator pump with a Stenner, and the carbon filter with a new unit.

We have an old Well-X-Trol pressure tank that has worked amazingly well, and is approaching 30 years old now, so I already have a new Well-X-Trol tank on the way.

Which leaves me to the contact tank, and pressure switch to go before doing all the plumbing.

Seems that most of the contact/retention tanks are a poly construction now?  Any recommendations on brands to look at or stay away from?

Any recommendations on a good pressure switch?

I don't mind spending a little more for quality parts that will last, and a lot of web searches end up leading to distributors.

Thanks.

The only pressure switches I've ever used have been the Square D switches.
They go up every once in awhile, but otherwise they've always seemed to work well and be readily available.

Square D is good stuff, here those pressure switches are available at Lowes. You didn't mention a motor starter, that is the one part I have replaced more times than anything else on my system. The capacitor is the weak link and can be replaced independent of the other parts but I just keep a new starter assembly on hand.  The one I use is a Franklin Electric, the box with the terminals is bolted to the wall so all I have to change when it goes out is the cover that has the capacitor and other components attached to it.

Thanks for the replies.  I'll check into Square D switches then.

Didn't really know about the motor starters being a weak link, still learning about having a well, so that's good to know, thanks.
