How to Diagnose & Fix Lost Water Pressure + Water Pump & Tank Repair Cost Estimates WaterAPedia © How to diagnose loss of water pressure or loss of water in a building How to decide if water pump replacement is needed How to decide if water tank replacement is necessary Typical cost of various well, pump, and water tank repairs.

This article describes questions and answers from and to a homeowner who lost water pressure. The basics 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.

• Bad or No water pressure? See WATER PRESSURE LOSS DIAGNOSIS GUIDE for a step by step detailed guide to diagnosing and correcting bad water pressure or total loss of water pressure. Before changing a water pump or control, we need to know why the water pressure or water flow is poor.
• Intermittent water pump cycling is discussed at Intermittent Water Pump Cycling When No Water is Running - this means that the water pump comes on for no apparent reason.
• Short cycling of a water pump means that the water pump turns on and off too rapidly or too frequently when water is being run in the building. See What Causes 'Water Pump Short Cycling' and Water Tank Repairs: Diagnose 'Water Pump Short Cycling'.
• Loss of water pressure means that the pressure with which water enters a plumbing fixture has become too slow, or is sometimes too slow or weak in water flow rate, or water flow may stop entirely. See Water Pump Problems? How to Diagnose & Repair Poor or No Water Pressure.
• Details on how to repair the water pump pressure control switch are discussed at How to Repair the Water Pump Pressure Control SwitchThe illustration at page top is courtesy of Carson Dunlop, Inc. in Toronto.
• How to boost water pressure in a building by installing a pressure booster pump and pressure tank is discussed in detail at PUMP, WATER PRESSURE BOOSTER

If the building water supply stops and takes minutes to hours to recover, you may have problem with the well flow rate. But the problem of lost water supply and pressure could be more mechanical: a bad well pump. The well pump, in turn, could have been damaged or hastened to the end of its life by a bad water pressure tank which has caused well pump short-cycling. Short cycling of the pump motor can burn up the pump relay control.

Loss of Well Water Pressure or Poor Water Supply - Diagnosis & Repair Guide

Questions about well repairs from a homeowner who lost water pressure and supply

The following is an actual case of a correspondent who lost water pressure and called a well and plumbing contractor who made several repairs. At the end of the repair water pressure and supply were restored but the owner had a bit of "sticker shock" when he saw the bill. He wrote to ask our opinion. Our reply, which follows the owner's note below, reviews the diagnosis, repair, and repair costs for this well pump and water tank replacement project.

Advice to a homeowner about water tank replacement and well pump replacement diagnosis, repair procedure and repair cost

In the following article sections we will review the repair items, procedures, and costs, but we must recognize that by remote email we could be missing something important and thus be WAY wrong.

How might a bad water pressure tank be related to water pressure or water supply loss symptoms

1. A bad or defective water pressure tank or water tank bladder can cause well pump short cycling which in turn is hard on the pump (damages the pump) and, especially with an older pump, might push it over the edge of failure. When the water pump fails the building will lose water supply completely (unless it is served by an artesian well).
2. A water pump might be at end of its life and about to burn up but still work after a cool-down cycle (some pumps have a thermal overload that shuts them off and an automatic reset - especially one that is inaccessible such as a submersible). In this case water pressure and supply will return after the cool-down problem but the failure is likely to be recurrent.
3. To review loss of air charge, water pump short cycling, water pump pressure control settings, and other water tank repairs be sure to see WATER PUMP & WATER TANK REPAIRS
