oh i see, the more complex ones, which have thermostatic control and thus are a lot more safer. basically the shower then varies how many volts go to the element, depending on how high the temp is!?

What are the reasons why a RCD (ie for en electric shower, etc) would trip/cut out? and if so, are they easily re-settable manually?? Thanks for any help

ok thanks for the info. basically: with the shower off, the solenoid is closed and water cannot enter the shower unit. thus it is a safety device, as if the micro/flow switch sticks, then no water (even a small amount/flow) will be able to flow through it. i thought that the element in the...

oh i see, the dial doesn't fully shut the water off. ok, thanks for explaining that. one other thing though: if the flow is too low, the element may not heat up (the pressure would be too low to activate the micro/flow switch). so how does the solenoid stop people getting scalded then...

i know this - but why the need? how comes the dial is not sufficient enough, like for an instanteneous water heater? wouldn't turning the dial not just allow water through and do the same job? i don't get what the point of the solenoid is? ........

One quick question for any experts out there who may know: What is the point of a solenoid valve in an electric shower? If the water flows through the unit and the pressure of the mains water going through it activates a micro/flow switch that puts the power on to the element anyway...

Hi Close coupled toilet. Woouldn't flush properley-took a few long flushed to get it to work! So changed the siphon. The cistern is slim(ish) and old. The new siphon caught the float arm (plastic, thickish) on the way up, so I used the original siphon and put the new diaphragm from the...

Hi all From your experience, what is the best set to buy for tightening nuts, ie back nuts, tap connectors, etc in tight spaces. I really need to get a kit after recent problems with the bulky adjustable basin wrench!! The Jaw Dropper set from Screwfix and also BES ( I presume the BES...

Hi Yes I know they turn the heat to the rad down!!!!!!! but the room stat will turn off the boiler when the room temp is reached,not the TRV. so the boiler will continue to fire no matter if some rads with TRVs are off! I suppose a modulating modern boiler would ... but a normal boiler...

Is the Domestic Heating Compliance Guide as strong as the Building Regs Part L1 for heating systems/design? Or is it like British Standards, like a guidance? I was looking for some info on the DOmestic Heating Compliance Guide (as I believe it is a new thing), as I am interested in what it...

ok, will do, then when i undo the iso vales, if there is a slight dribble, will just nip them up a tiny bit more!! :D but won't overtighten!!

the originals were fibre type. sorry for my ignorance, but when you say nip them and no need to hang, you mean just tighten gently and not overdo it?? thanks for helping guys.

ok thanks for that. i think they are reddish in colour. what is epdm? never heard of them before! do wickes stock them usually? where can i get some from.?

sorry i know this is probably a stupid question but i want to make sure i get the right size washer! ... i took my pump out today, after isloating the valves either side, and when replaced, a small dribble leaked from the top union nut. so the washer seal has been broken! what size washer do...

does anyone have any info on the "Economy 7" immersion heater and how it works, etc? Do you have to have 2 immersion heaters, one as a backup for this, and how do you get it connected to a cheap tariff rate?? is it old-school now? thanks for any info available.

after searching the net i have come up with the reason: it is to ensure that the vent pipe is also at the neutral point in the system (any more than a 150mm gap would not mean it is also at the neutral point). anyone else know of this?

:) hope the water holds when i'm bunging!!! bought the drayton set from b & q for £12 a few months ago!!

pump overrun removes residual heat from the boiler's heat exchanger when the boiler has stopped firing - this protects the boiler and stops "kettling" sounds happening also. usually found with modern, low-water content boilers. will be pre-wired up to the boiler's pcb when boiler is purchased.

ok will do. will get a new valve tomorrow from screwfix and fit it. will try and bung feed and vent in f and e cistern!!

yeah the case feels quite warm. it is honeywell - does this make much of a diff?.. sorry, maybe the ball is jammed as you say. do i need a whole new valve?
