This article describes gently shaking the well tank to determine if it contains water as part of diagnosing lost water pressure at a building . 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. © 2009 Daniel Friedman, All Rights Reserved.

Diagnosing loss of water or loss of water pressure in a building - shaking the water pressure tankOne can become easily confused by the diagnosis offered by simply "shaking" a water pressure tank. Shaking the tank can tell you that the water tank is empty but not why the water tank is empty. There may be a trick to this but we don't see how shaking the water pressure tank diagnoses a ruptured bladder or other very specific causes of the absence of water, but as a starting point, gently shaking the well tank can, however, tell us some things about the state of the building water supply system. We use this procedure often, by gently shaking or wiggling the well tank to see what's going on. If the well tank is at its normal "full" level of water it will be heavy and chances are you won't move the water tank at all. We also know that the water pump has probably shut off at its normal "cut out" pressure recently since running water in the building will empty the well tank in just a minute or three. If the well tank is empty or nearly so, it is quite light and can be easily moved. Recently when we were restoring water to a home that had been winterized, we tried turning on the well pump and we heard the pump motor run. We gently wiggled the water tank and learned that it was empty, so we figured that the pump was not delivering water - in fact the pump had lost prime. We quickly shut off the pump motor so as to avoid damaging it. Then we primed the well pump. That was all we needed to do to get the water system working again. Be careful: do not wildly shake the well tank nor any other plumbing component since doing so can cause a pipe to break or at least leak. What Does it Mean if Our Well Tank is Empty?The water tank could be empty simply because you ran all of its water out into the home and the water pump never came on to replenish the water supply. Some of the possible causes of an empty water tank and no water in the home include: We discuss in detail how to diagnose loss of water pressure or how to diagnose and fix poor water pressure at Diagnosing loss of water - be sure to read that article. Some examples of what we discuss there are listed just below:
