i was just testing it and fiddling about and curious really! well there was nothing else to do today! 2 crappy footie matches on that weren't exactly mouth watering!! but that was about it! :lol:

:oops: I was just testing my valve and it all started from there really ... curioisty i suppose. thank you all for your replies and help. it has been appreicated very much. btw - what do you mean sticking is intermittent (i know what intermittent) but what exactly would be...

thanks seco services for your help. so basically it is is mid position now until i turn it off and back on again to reset it. have just turned hot water only on again (reset it as you said) and it is like before, resistance at first when pushed across, so it is working correctly. i...

Hi I put HOT WATER only on and the valve had resistance when moving the lever to the MAN (OPEN) poisiton. but when i returned it by hand again to AUTO there was no resistance felt and then when again pushed across to MAN (OPEN) still no further resistance .. why is this?

Hi I have just tested my motorised valve (HONEYWELL 3 port mid poisiton type) - the HW and HTG are both off but I pushed the lever arm across to MAN and i felt resistance... on return there was no resistance and then when i moved it across again to MAN there was still no more resistance...

from what I have learned and gathered (from this forum and from previous knowledge, etc), motorised valves have quite a few things that can go wrong with them for eg, motor burnt out, shaft seized, valve not closing properley allowing hot water to pass through it, etc and there are also many...

got it now !!!! thanks! the grey wire is a permnanent live which allows the orange to become live when the switch is made (switched live) (thus putting power on to pump and boiler)! i suppose another fault is the valve not shutting properley as the return spring may seize up or not...

ok - a bit confused here!!! :) so from what i have read and understand this is how it works: the stat (cyl or room) calls, and the brown wire becomes switched live. this then puts power on to the valve motor which motors across and makes the grey wire close the auxiliary switch when...

right, so the grey wire needs to be live (or the valve will not work). so when the brown wire is live (when the stat is calling), the motor motors across, and closes the auxiliary switch which puts power on to orange (to start pump/boiler). but the auxiliary switch needs the grey wire to be...

2 basic questions please if any of you have any advice? 1) what is the best way to clean a blocked/partially blocked microbore manifold? 2) a 2 port motorised valve (HONEYWELL) has grey as permanent live (unlike a 3 port mid position does). why is this? am i right in thinking that...

Thanks all for your help. I think I have a partial blockage, as the radiators upstairs do bleed a bit, but the water is not of any real pressure (not as it normally would be) and also after a few seconds it just stops. I take it this means a partial blockage? I may have to drain the rest...

there are a lot of things to take into account - for example the 150mm distance between the vent/feed connection (for a commonly used close coupled system) and either the t-ee piece of an air separator should be used to join them the min. of 1 metre from the highest part of the system...

Thanks for your replies John - I have bled the rads and most of them have not much water coming out and not at any pressure at all. This led me to believe it is a blocked cold feed, especially now I have seen the sludgy muck in the F & E cistern as well. Water does circulate (or it must...

Hello... My heating (on in the mornings currently) and hot water are taking longer to heat up. I suppose this has been gradual but now is time to act I think. I have read about possibly having a blocked cold feed (from this site). After looking into my F & E cistern I have noticed a bit...

sealed systems do require topping up though now and again, due to water loss from evaporation, etc i believe...

I have heard about these econmy 7 immersion heaters. There must be a timer installed somwhere - it would not be able to work otherwise peoperley on economy 7. where the wire joins the connection unit, between that and the immersion heater or between that and the consumer unit there should be...

yes they are jus the normal hard rubber black tap washers! unbelievable! Maybe i should buy a whole set and surely one will match!! or big bigger? should i cut it up using a pair of scissors? Thanks for your reply.

would the fernox work for a doughnut washer that leaks a little when re-assembled after changing a siphon?

i guess nobody knows how to deal with this problem then?! :?

Please can any plumbers help me? I am loosing my patience! I am trying to do the simplest of jobs - change a washing on a dripping bathroom tap. It is a pillar tap - the hot side. Obviously the washer needs replacing. I know how to do this and have the taps off again, for about the...
