Is this pipe that is reasonable for the pressure? The only time I ever asked about this was use of that very lightweight plastic pipe you see on the lawn irrigation aisle at Home Depot. It's been awhile but when I asked the designers' if this pipe was rated for 90 psi in one case, and 110 psi in another, they changed it without answering my question.
It's somewhat like an excess pressure pump. The pump has a UL listing like my table lamp that addresses shock and fire hazard. But it isn't listed for reliability. If the pump fails the system still works. The downside may be an unwanted alarm. Will main drain pass water to an acceptable location without breaking and flooding the building. Once past the valve rules change. > On Mar 27, 2017, at 12:46, rongreenman . <[email protected]> wrote: > > More important question.
