It looks to me like it's a secondary return for the hot water (normally used on larger properties like hotels to prevent dead legs). Don't file the lip off because it's been specially made to take a union (e.g. 22mm Y65). I can't see any reason why you cannot use it as the hot feed for your...

If the kitchen tap is of the quarter turn lever type I would swop it or change the cartridge. Water hammer is very common fault with these taps when they are worn. Water hammer noise tends to be a single "Bump bang" when the tap is turned off; whilst a kettling noise is more of a prolonged...

If it's 14 years old probably turn the gas off to it and label it unsafe!

British gas do operate under a hierarchy regime with their employees which I personally would find almost impossible to work under (much preferring a consensual working arrangement), so don't despair because a BG job will not suit everyone. It's highly likely the persons doing the interview...

Or even a ACOPS qualified engineer! o_O

That's a lot of stored H/W there Jason (maybe fitting a smaller cylinder would be the best way to save a few quid). Out of interest what type of boiler have you got?

Whilst I can understand what you are all are saying here and a lot of customers do have a bad attitude! Do they also blame the last mechanic who fixed their car when something else goes wrong with it or even their doctor when they become unwell? No! But it is a fact of our trade that they're...

I'm thinking that you should have your flow rate on your mains supply checked by the water board. A simple basic test you can try yourself is to fully turn on your wash hand basin cold tap and watch it for a...

I always fit radiators 12mm above the skirting so that the customer can dust the top of the skirting (have done so since my apprenticeship). However, removing rads for decorating is a total ball-ache even for experienced tradesman. Advice tuck the wall paper down behind the top of the rad...

It refers to the amount of resistance of the pipework on the circuit supplying the index radiator. The ind...what radiator :? :lol: sevotech,

Glad to hear that because I do get a lot of complaints of the water on unvented systems being cloudy at first draw-off. Must be the anode causing this, which after all is only doing what it's meant to do (corrode). Quite a fascinating subject is this royalty amongst metals. servotech,

What, yeah, how the hell did you know that? Cost me over £1000 quid mind you - which meant it was Bognor rather that the Bahamas for this years holiday! Hobson's choice yet again for the British working man I guess. :( servotech,

Check the central heating pump and room stat (if fitted). servotech,

To quote an old adage is "if you want a job doing right then do it yourself"! Sounds like you've done a good job there Lazy. All the fuss over unvented cylinders is simply making sure the 3 safety devices are all fitted and working correctly. Did you experience any discolouration to the...

It's your washing machine - put some "Dr Beckmans" through it on a 90 degree wash cycle. servotech,

Highly likely that the plumber who turned off the mains turned the stop tap back on full when he turned your water supply back on - try turning it down (anti-clockwise) first. servotech,

You could simply replace the primatic cylinder with an indirect copper one (keep things vented) and fit the new heating header tank in the loft. Old fashioned, yet very reliable and a days work at the most. Depends on your budget I suppose. servotech,

Whatever you decide to use Adgeo be wary if they have a twist/lockable action that you do indeed tighten/lock them into place. This is were the DIYers always come unstuck. servotech,

The H/W side of a combi' boiler is instantaneous. Example - you open up the hot water tap and the boiler fires up you close the tap and the combi' switches off (no pump involved). servotech,

So we're now back to the AP switch. Please do keep us posted on the out come!
