I open up the pump. the drum spins ok it's not seized. Any idea?

Magnet doesn't stick. There is water in the tank and the ball valve moves freely.

I turn the HW on and it ignited for a couple of minutes. As the picture below, the flow pipe, which is in the red box get a bit warm and the blue not warm at all. Could this be the pump is not working?

You meant, have i bleed the rad? Yes i did.

That's the one that goes to one of the radiators in the toilet. Not sure what is called, i think they said it is a leak system or something ??

Yes it is. It has pipes that go to back boiler before, which I capped it. And also one radiator always get hot when the HW is on.

Not sure that it's the second pump. Only can find one. This boiler could only run HW only or CH & HW. It can't run on CH only. And it's a gravy system with a storage cylinder.

Yes, it is the HW return.

I off the switch and bleed the pump, however, the same thing happens. It fires up for a couple of minutes and went off again.

I got an illustration of it here.

Hiya, My HW (hot water) not working after I drained my CH (Central Heating). I released all the air pressure in all radiators. When I set the control to just HW, I can see the fire start for a couple of minutes and then it went off. Any idea why? Should I bleed the myson unit five pump? Is...

Hi All, I would appreciate if anyone could advise me on what sort of filler would be the best to fill up those gaps between the stairs? Btw, I plan to strip off the paint and stain it. .

Ya, there is no isolated valve below the taps. So, I going to change the taps and install the isolation connector as well.

Hiya, I would like to change my taps (doesn't have isolation valve) and would like to know if anyone knows how or can I isolate the system (Santon Premier Plus) by not drain all the hot water in the tank? Thanks,

Do i need to replace the cartridge as well?
