For all us perfectionists out there.

I work in Manchester, this building was completed about 5 years ago and the company I work for moved in right away. Now, tell me if this is a great install or just someone just joining the dots (well, pipes actually).
I know that on other sinks there are pipes which add cold water feeds to the hot pipes to keep the temps down (helps prevent scalding) but I just can't make head nor tail of this.

Obviously a maintenance contract is in place so why would you want to know?
Standard TMV supplying basin hot supply.
Supplies exiting through wall would be hot supply/secondary return.
PRV installed to hot supply upstream of TMV.

If I remember correctly, it was a certain John Prescott as Deputy Prime Minister, that ordered, (among other things), that temperature balancing valves must be fitted to public washrooms. Probably one of his better ideas, if it prevents scalding then can only be a good thing.

The plethora of compressions fittings have been used as chromed copper was specified.

I was thinking there must be a more elegant solution though.
Having seen so many shortcuts and bad workmanship makes me wonder how the works got passed by the inspectors. Once completed (at £114m after £4m fine for late completion) the company sold it for £150m only to lease it back at £12m per annum for the first 5 years and then an incremental increase every 5 years. 3 years in and the profit was gone and the company is still responsible for all maintenance and repair costs.
Mad I say, mad !

All of it must be made easy to service...but they could have fitted it behind access panels or better still behind the wall with access behind.
