Intermitant Waterpump

[Guest]

When running the watertap on my Moody 333 the waterpump comes on then off and the water spurts intermittently from the tap. It does'nt run all the time. rrrrr off rrrrr off rrrrr and so on. Can anyone advise where the problem is. Its a good reason to save on water but not very convenient. With thanks.

If your system has been set up properly you will have a pressure tank which is used to provide a steady stream with the pump working ocassionally. You may find that the rubber diaphram inside this tank has deteriorated or just lost its pressure. You will find a valve (bicycle type) which you can use to re-pressurise to tank ( I think it should be about 2 - 3 psi). If that doesn't work and yours is bust, then I have a spare.

Alternatively, if you have an in-line filter (eg active carbon) it may be clogged preventing waterflow to the inlet side of your pump.

The water pumps on Moodys' have a small filter by the pump, if this gets clogged up the symptoms you describe can occur. It is unlikely on a 333 that it has an accumulator tank as suggested in another post.

hope this helps

RE:accumulator Tank Pressure

If you have an accumulator tank, for optimum proformance of your water pump, the tank should be set to just above the cut in pressureof that pump. So if the cut in pressure of your pump is 8psi. (if you have an engine heated calorefier the working pressure of your domestic system should be above the running pressue of the engine heating it. Then if you get a leak in your calrefier tank you wont get antifreeze in your domestic system!!!!! Obviously in you dont have an engine it doesn't matter!!) the accumulator tank should be 9-10 psi.
as stated before check the filter inline but also check the pump settings. if you dont have one its a good idea to have a preasure guage somewhere easily accesable in your cold line afer the pump / accumulator tank.
Modern day pumps cut in at about 10-12psi and cut out at aprox 20psi obvioiusly this depends on the system fitted

I hope this helps
