CH Pump
Tis mega noisy vibration I'm getting...
well I've taken off the pump and found it rattles Pump vanes all look intact, but it has a sideways movement If you remove the grub screw on the front, poke in a screwdriver you can move the pump inside about 5 mm in and out bearing gone? or should they have this movement? Is there a way to check the pump before I buy another? TIA -- Vass |

OK it means there is crap in the system, quite probably the old wicks boiler is internally decomposing but its getting changed this summer so I will perform a proper flush then. -- Vass |

TIA The shaft end float you mention, is quite normal as is some leakage on older pumps. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |
