Hello. I found this site doing some online research regarding several well-related issues. Unfortunately, I know absolutely nothing about plumbing and wells - although I've learned quite a bit in the last five years. I still have a lot to learn and can't afford to shell out anymore to my plumber until I have a very good understanding of what needs to be done. I've spent too much already on exploratory repairs. I have a tankless water heater that is used to heat the water and the house. I've replaced the heater coils once so far due to water hardness - not a big deal - the house is 8 years old. I flush the rusco filter every 3 - 4 days. - spin down 1000 micron - go through 6 filters a year. I rinse out the faucet spouts twice a month to clear collecting sand. I also find what looks like sand in the bathtub after running a bath and letting the water sit for a few minutes. Replaced my shower head every 2 - 3 months (or clean it out with a toothpick). I've replaced both diverter valves in the showers and learned the pipes upstairs are reverse in the process. I had a stainless steel whole house filter installed (not sure if it's before the tank or after) I do know it's connected to the pipe coming out of the wall - i'm guessing it was installed in front of the tank. I flush the whole house filter same time I flush the rusco sediment filter. I had hoped the whole house filter would solve the problem - I thought it might take awhile if there is sand build-up in the tank or pipes but it's been 2 years now. I can not run the upstairs shower and downstairs at the same time - the upstairs shower will not have (0) water pressure. My plumber has suggested installing a hot water storage tank but there is no room in the boiler room for one and he has also suggested raising the pump. Raising the pump sounded good but it's expensive. Is that something that can be done easily by the homeowner? Any idea of what is causing the sediment issue and little water pressure? Any thoughts and/or suggestions would be greatly appreciated. Thanks.
