I hope I'm reasonably familiar with the current regs - smoke alarms not to be within 30cm of a light fittings or walls, alarms to be mounted within 3m of all bedroom doors, etc. However I'm a little confused by the "Max 7.5m from any door to a habitable room" clause. I have a attached a rough...

Hi all. As I understand the "rules" you need to fit a double check valve to an electric shower if the shower head could potentially dangle in the bath. Correct? Now, on the shower I've just fitted Triton kindly provide a soap dish thingy that clips onto the bar, and, provided you thread the...

OK, here's the scenario. 3 storey property - commercial on the ground floor, 2 floor maisonette above. The maisonette has it's own supply, meter, CU, etc, located inside the property, BUT the smoke alarms (proper battery/mains interlinked jobs) are fed from the CU in the commercial property...

Hopefully a simple question...... New electric shower fitted in bathroom. The work is notifiable as there has been other rewiring done too. All accessible metalwork will be eq bonded, running back to the shower mains supply (ceiling mounted dp switch) BUT..... do I need to bond the water...

I will shortly be installing a Gledhill Boilermate 2000 on an oil fired CH system with all TRVs. Before buying the Gledhill I was intending installing a std cylinder and with this in mind I bought a Danfoss Alpha pump to cope with the TRVs. Question - can I install the Alpha in place of the...

Firstly, this is not a question requiring a solution - its just to satisfy my curiosity....! I am replacing a 20 year old oil boiler which had 4 pipes running to it - indiect cylinder coil F&R, CH F&R. I was powerflushing the system today and couldn't understand why the bathroom rad...

I'm fitting a new Biasi Riva 26kw Condensing Combi Boiler (well the pros will fit the boiler, but I'm doing the plumbing) and have a couple of questions: 1 - CH will comprise 7 or 8 rads across 2 floors. My plan is 22mm in & out of boiler, 22mm equal Ts to LHS & RHS, manifolds at each end to...

A quick and hopefully easily answered question..... I am installing a new 26KW oil fired boiler and a 180/210 litre thermal store. Connections on boiler and store are 22mm/1". It may be gravity fed, but more likely pumped. Should I use 22 or 28mm pipe? I am assuming 28mm with converters...

I need to replace my duff oil boiler but having read a load of stuff, I am not convinced that a condensing unit is the way to go. Convince me by all means, but: - I'm not bothered by the legislation - I can work round that - I just want the most cost effective solution. - I will be...

'm planning on installing a thermal store/heat store and I understand I should have 20 litres/min incoming mains flow rate min, BUT what's the effect if my flow rate is lower? I can't check it till the weekend. If it comes in at less than 20 l/m does this affect the function of the store, or...

I am renewing a duff boiler and thought I may as well change the old pump while I'm at it. Thing is, I've realised the existing pump is potentially undersized for the number of rads. Its a 5 bed house with 23 rads. They are all on TRVs but generally 5 or 6 are turned fully off, but even then...
