I am currently going to be installing a new well water pressure tank and of course a new tee, cross, or manifold for the well water plumbing system of my house. I will essentially start with a new water well tank using a reputable brand name consisting of wound fibreglass and plastic this time rather than steel. The new tank of course comes with a bladder and be precharged with air.

The line coming into the house is 1" galvanized and is in surprisingly good shape considering the hardness of the water and age of the pipe. But in the past, all the galvanized piping near the pressure tank and tees for switches and gauges has been a challenge as it becomes clogged with rust and iron and mineral deposits. Eventually, switches and gauges become inoperable as these pipes get plugged up over the years.

The current system will consist of 1" galvanized buried pipe outside from well casing converting to a section of 1" pvc at tank in house reducing to 3/4 copper to household system.

For the above reason, this time I will plumb in the pressure tank with 1" pvc fittings. I will utilize a series of 1" pvc tee's bushing them down individually for a pressure gauge and switch, boiler drain and relief valve. The tank is in a reasonably out of the way location but the thought of relying on something new and plastic scares me when I consider plastic pipe is not nearlly as sturdy as galvanized. The advantage I seek is plastic shculd resist the tendency to become plugged due to corrosion and mineral deposit from my well. This area of piping is for cold water only of course.

Did I make a good choice and can anybody offer any other comments one way or the other. Thanks in advance. I just don't want this stuff to break or fail unexptedly but then,why would it?

"I consider plastic pipe is not nearlly as sturdy as galvanized."
While it's true you can smack PVC with a hammer and crack it PVC, Schedule#40 will not build up rust in the pipe walls and will not deteriorate with age as will galvanized. All things considered PVC is your best bet. While bladder tanks come precharged the correct setting for the air pressure is two pounds under the cut in PSI on the control box. If you have a 30 PSI cut in and a 50 PSI cut out on the control box the setting on the bladder tank should be 28 PSI. good luck, Tom

ThanksTom

I am not sure my reassurance adds much on top of Tom's answer, but I did largely the same about 5 years ago, and no problems since. Biggest difference is I have copper in the house, but PVC clear to the pump at the bottom of the well. My tank is in the safety of our crawl space.
