Both the Home Depot website and the WaterWorker website have very good insight as to calculating water tank size. If there is still some confusion, hire a licensed plumber.
Yes. From the Installation Manual: "Set the precharge pressure in the tank to be 1 to 2 psi below the pressure switch pump cut-in setting. First, look inside the cap to the pressure switch to determine the pump cut-in setting. It should say “20/40” or “30/50” or the like. The pressure in the tank should be adjusted to be 2 psi below the lower of these two numbers. That is, the tank pressure should be set at about 18 psi if the cap indicates a cut-in setting of 20/40, or set at about 28 if the cap indicates a setting of 30/50."
Yes it will work however, a 1 1/4 attachment will be needed to downside spout at tank!
it has to be installed upright.
Yes, Install filtration units and other devices downstream of the tank. Inlet>Tank>Filter>
I think the only advantage to adding a tank to a city water line would be to possibly smooth out any pressure fluctuations or temporary drops, as it would not boost pressure beyond that fed into it by the incoming water line.
22 inches round
i believe the base measures 24" which would make the tank roughly 25". For a 62 gallon tank i fit m8ne in a rather tight area. I believe they all measure the same width...its the hieght that changes with the increase of gallon size. The hieght isnt over 48"...i do not have access to tank to g8ve oerfect measurements.Shown with install k8i that is purchased separately.
I don't believe these tanks are designed to be buried. Especially in direct contact with the ground soil. Even the tiniest flaw or scratch in the paint coating would be an avenue for corrosion to start. The corrosion would then quickly compromise the tank and cause it to burst. It is best to place the tanks in a protected area out of the elements and freezing temps (usually in a crawl space or garage/out building). If a person was to bury it, there would be no way to inspect it or maintain it without having to dig it up time and again.
