Low water volume on city water
I have an old 2 story house on city water in an old part of town, with very very low water volume. The old iron pipe feeding the house is only 1/2 inch and is shared with the neighbors house which is vacant. The 100 year old city main is under a city street which is also a highway, so the cost to replace the main to the house is over $12,000.00. The city says their main is not scheduled for replacement in the near future, and since I am responsible for the line to their main, the cost of replacement is mine. Thus I am looking for an alternative solution. The main bathroom is on the second story (which barely makes it possible to use the shower), the half bath is in the basement and laundry is in the kitchen on the main floor. It takes forever to fill something like the washer or the tub. I have been looking at adding a Flotec pressuremate pump to the house along with some sort of water tank for storage of incoming water. I don't think a pressure tank alone will hold enough water to keep up with the use of multiple items, since the volume coming into the house is so low. My question is what type of storage tank is recommended and how many gallons for a 3 bed 1 1/2 bath house? Would this pump be sufficient with a large supply of incoming water, or would a pressure tank also be needed? Or, does someone have a better solution?
