In my own home for quality and dependability and peace of mind and a great price and parts readily available DELTA is my choice

Thanks will go with Delta. Do you have an answer to my other question...in order to extend the life of my well pump should I increase well-x-trol tank capacity from 4.4 gal to say 20 gal OR install a constant pressure system with cycle stop valve (new to me).Thanks again.

I do not do country plumbing BUT when I install a pump for a high rise building I use either a roof tank and let gravity feed the building or use a hydro pneumatic tank with a cut in and cut out setting depending on applications and manufacturers recommendations.
