[QUOTE="f0ster, post: 7648054, member: 66372"] better still is to fit a magnetic filter, you will find most of the discolouration is magnetic sludge, fitting a mag filter traps this sludge and extends the life of the pump, pumps have the rotor/armature made of permanent magnets encased in a stainless steel tube, the tubular housing surrounding the rotor is fed with boiler water via a drilling down the rotor shaft (usually ceramic) any magnetic particles passing the drilling get attracted in and then stick to the rotor eventually making it seize up. wilo pumps are very prone to the stainless rotor tube wearing through allowing water to corrode the magnets which makes it swell up and jam in the housing, taking it apart and cleaning it is a waste of time unless you catch it soon enough, if your wilo pump rattles slightly it is already too late. either way get the inhibitor in anyway, you can test the inhibitor with a ph meter, if you are on borehole water for the boiler get it tested for quality asap.
