This article explains how to Diagnose and Cure Bad Water Pressure Due to Clogged Water Supply Pipes - how to diagnose the loss of water pressure and the need for a replacement water pressure tank and water pump. The process of diagnosis and the costs of the repair are explained. Consumer advice on saving money on well repair costs includes a review of the parts and labor costs of a typical well pump and pressure tank replacement case.

Clogged water supply piping can cause poor water flow in a building. This can occur suddenly from debris clogging a delivery pipe, often at a turn or "elbow" in the piping, but that's not common.

If the building water supply piping is blocked usually this is a long-standing problem.
Examples of causes of poor water pressure due to blocked pipes include
The sketch (above left), courtesy of Carson Dunlop Associates shows how galvanized steel water supply piping becomes clogged from rusting or mineral deposits. Also see WATER PIPE CLOG DIAGNOSIS and WATER PIPE CLOG REPAIR. Also see WATER PRESSURE LOSS DIAGNOSIS & REPAIR in a building and see MUNICIPAL WATER PRESSURE DIAGNOSIS or WELL WATER PRESSURE DIAGNOSISwhere we describe the effects of clogged piping on water flow and offer remedies for this problem. If only hot water pressure and flow are poor, also see CLOGGED SUPPLY PIPES, HOT WATER.
There are two useful diagnostic tricks to determine if building water piping is clogged:
A main water supply pipe failure between the municipal water main in the street (or from a private well) and water supply pipes in the building the building, can occur, perhaps by leaking or by becoming clogged with rust or minerals so that water is not being delivered to the home at good pressure or not at all (if the water line has burst).
In cold climates, the water supply line may have frozen outside or even in the building at an un-heated location.
