Question DetailsAsked on 12/23/2017

What can cause no cold or hot coming water to faucets?

I have a Well with submersible pump, cold water holding tank and hot water tank. Tanks have water in them but won’t come out of faucets. The pressure points and dial are showing 30 psi of pressure.

Do you have the same question? Follow this Question

First check that some small kid, practical joker, or vandal has not turned off a valve between the well head and the house. Also check with other family members if they shut one off and forgot to tell you, because there was a leak or such.

Tanks could have water in them but there would not be flow unless the faucets are downhill from the tanks - usually the water in the tanks flows to the faucets because there is pump pressure pushing other water to the tanks, forcing the water in them to the fauceets. No pressure coming to the tanks, no flow out (except by opening the drain valves at the bottom, which without incoming pressure would just drain the water out of the tank and the house pipes which are higher elevation than that.

Then all you (or a plumber) can do is start at the wellhead and work toward the house, checking for water pressure and flow at each hise bib or drain xxxx along the way - bearing in mind if the tanks are pressure tanks (not open to the air at the top) they may have pressurized water in them until they drain off a bit.

Depending on where you have hose bibs or drain xxxx , may take opening up a fitting or to for the check.

Common possible causes, on the assumption that the pump is working and building pressure - meaning if you open the drain valve typically located right at the pressure gauge, it will flow at pressure indefinitely. If it flows there but rapidly drops off to no pressure, then could be the pressure you were seeing was just from the pressure tank and not the pump working, or well has run dry (water level fallen below the pump inlet).

Listed roughly in order of how common this is the source:

1) valve has been closed somewhere along the line

2) frozen pipe

3) backflow preventer or pressure regulator has corroded to the point of locking up, shutting off the flow

4) if you have a pressure tank, outlet has become blocked with sediment or rust

5) corrosion or iron algae or such buildup in the lines has blocked them off - but prior to total blockage you would have seen a reduction in flow during showers or such, as the pipe started blocking off

6) failed valve which has broken, blocking the water flow - pretty rare - most such failure result in the valve not being able to close, not popping from open to closed.

If you cannot track down the problem, then if water is coming out at drain valve at the gage when you open it and the pump runs and maintains pressure and flow there, Plumbing would be your Search the List category. If no water even at the wellhead orpressure very rapidly drops off and does not come back up because of the pump running, then a vendor in the Well and Pump would be the Search the lIst category I would call.
