BangkokRobert Posted September 21, 2014 Share Posted September 21, 2014 I'm renting a townhouse that has a pump to provide water pressure for the 2nd floor. Lately it's been cycling on and off all day and night. Any suggestions? Any names/companies you'd recommend for hiring to fix it? Thanks! Link to comment Share on other sites More sharing options...
Sayonarax Posted September 21, 2014 Share Posted September 21, 2014 Check the tank and make sure the valve with the float is not broken. Link to comment Share on other sites More sharing options...
BangkokRobert Posted September 21, 2014 Author Share Posted September 21, 2014 Ok! I'll try that as soon as I get home. Thanks! Link to comment Share on other sites More sharing options...
Gsxrnz Posted September 21, 2014 Share Posted September 21, 2014 (edited) If it's cycling on off all the time and you have all taps/faucets turned off, it implies that you either have a faulty pressure sensor/backflow valve in the pump, or that there is a broken pipe somewhere on the outlet side. Is water actually being consumed? If not, it implies a faulty sensor/valve in the pump. If water is being consumed from the cycling, you've got a leak/broken pipe somewhere. EDIT: And checking for a broken ballcock in the storage tank is irrelevant to the actual problem, although you will have to look into the tank to determine if water is entering the tank when the pump is cycling (and all known taps.faucets are closed) to determine if you have a leak on the outlet side of the pump. I suggest you turn off your pump, ensure the storage tank is filled or allow it to fill completely so that the ballcock valve is closed, then restart your pump and see what happens. I'm assuming that you actually have water pressure at the taps - if not it could be as simple as repriming the pump.

BangkokRobert Posted September 21, 2014 Author Share Posted September 21, 2014 There's no water being used or leaking anywhere that I have been able to find (could it be leaking under the foundation is the house?). Link to comment Share on other sites More sharing options...
lopburi3 Posted September 21, 2014 Share Posted September 21, 2014 I suspect this pump is to water lines rather than a water tank (and float valve) and if no leak may only need a recharge of the pressure tank (needs air pocket) so turn off electric and remove screw plug to allow water to flow out of tank until empty and then replace screw plug and power up - this should reset the air in tank.

BangkokRobert Posted September 21, 2014 Author Share Posted September 21, 2014 A man in a equipment showroom demonstrated something like that. He showed me a value on the side of a tank that could easily be taken off to drain the water. When I got home I found my pump didn't have side drains/valves like his. I did find one on the very top. I opened it and ....quickly flooded the room. Haha. I replaced the cap/plug. I didn't notice any change in the cycling behavior. Link to comment Share on other sites More sharing options...
Aussieroaming Posted September 21, 2014 Share Posted September 21, 2014 Yes agree..low pressure switch is activating and pulling in the pump contactor. First discount a water leak on the pump discharge side piping, if you have any in line strainers then make sure that they are cleaned as well as you can have a pressure drop across the inlet and outlet of the strainer. If it isn't those then pull the pressure switch out and make sure it's clean and free of debris. If it's clean then it's likely the pressure switch is u/s. Usually a buggered pressure switch is better replaced than trying to fix it. Link to comment Share on other sites More sharing options...

You are pumping from a holding tank with a check valve to prevent flow when pump is not drawing the water? Sounds as if may not be the case and you need to stop the input water flow and then open some taps to drain pressure in tank and then try removing the plug?
