are all the pumps the same? I know the flow rates may vary, but all do the same job? - this was from B and Q saying that I bought the correct pump, there are only 3 wires if I remember, how could I get this incorrect? any pointers as to what could be wrong - if I am correct in what I...

ok - so what your saying is that when the boiler is firng, to make the required temp, the pump runs to circulate it to the tank etc? when the temp is reached, does it run for a while after the boiler stops firing? its just that every time I check it in hot water mode, the pump is hot and...

Hi hadn't had to use the ch since last year, and due to the motorised valve breaking, had to change it and also the pump due to water shorting it and subsequently burning it out (possibly needs drying out) Fitted a new valve and pump When I put the central heating on, the pump appears to...

Hi hadn't had to use the ch since last year, and due to the motorised valve breaking, had to change it and also the pump due to water shorting it and subsequently burning it out (possibly needs drying out) Question when does the pump run? does it run with just central heating selected...

Hi Gas4you I think I may have got it a bit mixed up, and that I now think it is the pump running all night. the switch was on heating and hot water and the stat was turned down, so rads were cold. when does the pump run - under what conditions thanks

Hi I just had to replace the 3 way valve and the pump. The valve works fine - heating just the water or ch rads if selected. I changed this yesterday. However last night was aware that I think that the pump was continually running and also the boiler running. I don't think this is...

Hi All My story continued. Initial fault hot water working fine was turned on central heating switch and turn up roon stat and nothing happened looked at the honeywell motorised valve. It is T shaped. marked b, a and the one going down AB If I move the lever manually to its...

I will disconnect the new valve and see if it still trips out. If so then its the water. If not i am F****d. how do I work out the correct wiring?

Bought a b and q jobby wired it up as the original, only difference is that there wasnt an earth wire (plastic lid) Isolated left, right and above andbelow the pump, that is a foot below the valve. When removing the valve, water splashed over the terminal block containing lots of wires...

Hi I have a shut off valve left right of it and the down bit goes to the pump, and below this is a shut off valve - all manual would it be ok to isolate it this way? if i bought a b and q one, is the wiring standard? Thanks

Any ideas on price?

what colour is that? Too late, the blooming micro switch just fell apart!!! The valve I described, do I have to buy another honeywell, or will the local b and q do the job. is there only one type of unit available? Nick

Got that looked under the head and the gear doesnt look like it engages very well with the actuator part that turns. I buggered about with this a few years ago if i remember. also the double micro switch doesnt look the best. If i select just water, what voltages should i get? again any...

hot water working fine turn on central heating switch and turn up roon stat and nothing happens. looked at the honeywell motorised valve. It is T shaped. marked b, a and the one going down AB If I move the lever manually to its futhest extent, then the heating and pump kick in. If I...

what i mean then is is there a correct position in which to engage it after you have removed it/ seperated it. thanks

motorised valve this i believe controls hot water or water and central heating. If i remove the motor, how do i reconnect it so that i know the motor engages the valve correctly? thanks

Do you think it needs changing or just aligning?

The radiators getting hot as I said and then when I turned the stat down, the pump turned off. However I turned the stat back up, and nothing. So I touched the lever on the valve, just a touch, back towards its furthest point, asif un hooking it from curve. As I did I heard a click and it...

Hi Appolo boiler changed the thermocouple a few months ago as pilot light went out would not light. Had a few mvolts on there, but forum advised changing and this solved the problem. Here we go with my new problem hot water works fine, and seeing that I messed about with the motorised...

\the colour would be exactly what it says on the tin!!! ;-D
