In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
This question keeps coming up in different postings as to what pressure your local natural gas utility is guaranteeing you?
It used to be when I worked for the utility we gave 7" to 10" W.C. as an answer. I am now hearing 4" W.C. pressure. Be advised on demand water heaters, Mod/Cons etc can not run on those low pressures. So that limits what areas those can be installed.
I had a recent job for a church that needed 1,250,000 for the boiler the utility could only give us 5" pressure so we had to install a three inch pipe line to the boiler.
