Can someone explain the different pumping systems, tanks tankless etc... I have a cottage with a shallow well probably 30 feet. It currently has a
1/2hp jet pump and ~25 gallon tank. The tank is full of rust which in turn is coating the UV sterilizer bulb. I am going to replace everything. I noticed That jet pumps are sometimes call convertible, what does that mean? Some wells I have seen have 2 pipes in them, what system is this? I would like to go with a fibreglass tank and my local well driller says a 6 gallon size is plenty, why was there a ~25 gallon one put there originally? What about bladders, do all tanks have them? Some jet pumps are stainless steel, is that the entire pump housing or just the shaft. I have some apartment buildings and the domestic hot water system has to have a bronze circulating pump so why is drinking water from a well allowed to be pumped through a rusted cast iron jet pump? Also I see some pumps listed as not needing a tank, why is this. When are submersible pumps needed? Thanks for clearing up some of this for me.- posted
