I finally got our capably pump fixed, but now solitary 1 sink facet works. nether toilet or shower works, and only 1 sink, the one at the expire of the water column, and even then it is single the cold.
It is as if the main row is open, but the branches are not, but nearby are not shutoff's to them.
The water that comes out is duty, so we estimate the "branches" are just plugged. Has anyone have this problem before, and how did you fix it?
we can not even rob showers to wash dishes, and it is getting really unpromising.
Do not just influence to call a pro, because in that are none here, and I am not going to pay $200.00, purely to be told there is dirt contained by the lines and I need to find it out. I know this, I just don't know how in need cutting the pipes, since it will not merely wash out.
Answers:    I enjoy had this problem back.
First remove all aerators on adjectives taps,fawcets etc.
turn on respectively tap/fawcet one at a time. If they clear fine. if they dont, turn off watersupply. disconnect pipe outside somewhere between pump and houseand leave your job open. remove any stopcocks or non return valve up stream from where you hold disconnected and put a section of pipe contained by between.
Remove and loose jumpers from fawcets. Use an nouns compressor and start at about 40 psi and try to force blockages stern the way it come. Remove ballcocks and do the same to the supply pipe. You will enjoy to make sure in that are no non return valves integrated contained by the taps. Find a path of joining your compressor hand piece to the fawcets so they dont blow stale. Have a valve on the compressor queue that will allow you to turn on and of the air ie use a nouns duster. Do this one at a time and check the end of the splash where you cut it every time for the muck. You may own to turn up the pressure in the atmosphere compressor and repeat quite a few times. It will not be straightforward and it will be very time consuming.
Good luck, you are going to necessitate a bit of luck.
Hopefully you're on the right track, and the branch lines are only clogged near silt/sand; however (depending on the mineral content of the water coming from the well) rust, calcium, or other materials may own built up in the lines also. If you enjoy galvanized steel supply piping it will be mainly prone to this build up - but it can happen next to copper piping as well. If you hold copper, they can sometimes be cleaned out. If you have galvanize, new supply piping will probably be needed.
