I am struggling to understand about Balance cold Water do you know how does it work in the Megaflow system? what is the main cause if T&P constantly Dripping in the tundish Because what I recognized is that hot water cut off in the middle and just come and go out.

Here is an awful rough sketch of what I propose lol https://i.imgur.com/tisk9Vv.jpg

T into the 15mm plastic pipe with a speedfit T (yellow). Red signifies copper pipe. Speedfit elbow (yellow) to copper pipe (red). Then isolation valve (green) to copper pipe to double check valve (blue) to copper pipe to Speedfit elbow (yellow) which would connect to the tap pipe from outside. Sound OK? Sound awful?

Hi mate, do you remember this thread? https://www.diynot.com/diy/threads/need-a-feed-for-outside-tap.465578/page-2#post-3715005

I've decided to get round to it and wonder if I may ask another piece of advice?

Here’s an image of the pipe work under the sink. https://i.imgur.com/bNJhd87.jpg

I can bring the pipe in almost anywhere in there. So my question is this; if you were doing the job where would you T into?

Hi I read an old listing you commented on diverter valve on valiant 18t3wfh which is at the bottom of the boiler is it possible to still get a repair kit for this do you know the problem is when I call for hot water it is going to heating regards richard
