Removing an olive from some 15mm pipe will be very difficult. We are aware of the options such as olive puller, sawing off etc but we want to try and use a new isolator valve with the old olive in place as a first attempt. My friend who has done this before has used LS-X (probably because this...

That’s a good idea, thanks

I need to use a 300mm flexible/bendable 15mm copper pipe (the corrugated type that looks like a coil) but I have read that the copper is only 0.6mm thick and therefore weaker than normal 0.8mm copper. Would it be okay to use a plastic insert to strengthen it for compression and push-fit at its...

I read a article about water meters and their inherent non return valve. It seems that the distance between the boiler and the meter is significant. A longer run will allow heat to be absorbed and therefore not cause too much expansion thus not damaging the hydro block in the boiler. A short...

You make a good point, thanks. I suppose I could fit it on the hot water outlet and just see if it does the job Edit: Just thinking about it more, fitting on the input would solve BOTH scenarios - is that correct ?

What about putting a NRV on the hot water outlet of the combi as Tony suggested, would that also solve it ? (it would be very much easier plumbing) Thank you.
