Hi all.
My bath (soon to be replaced) has 1 unit comprising two separate taps for hot and cold AND a mixer shower unit attached to the top (its made by armitage shanks). It one where you flip a lever to stop the flow from the taps and force it to run from the handheld shower instead...
Anyway, for some reason the cold tap inlet pipe from under the floor has a 15mm tee running off it. This tee feeds INTO the hot water tap inlet pipe. I guess if you look at the other way round, there is a tee running from the hot inlet pipe to the cold inlet pipe. All pipes are 15mm plastic. Flow rate is good being served from combi boiler.
Having found this when removing the bath panel yesterday, it may explain why I get nice cold water when running the cold tap, but when you run the hot you get scalding water for about 20 seconds, then it runs cold. The only way to maintain hot water is to run it at a very low rate (20 mins to fill bath). I suspect though that this 'hot then cold' problem is to do with my 14 year old combi bolier being on the way out!
Irrespective, the 'tee; from hot to cold pipes has completely confused me. Why would there be a pipe running between the hot and cold inlets to the bath?
Does it have something to do with the mixer shower unit?
I need to understand this as the new bath will just have hot and cold taps, and I'm now not sure what amends I need to make.
I HAD assumed that hot pipe runs to hot tap, and cold runs to cold... or is that too simple?
