Does anyone know anything about Thermostatic Mixing Valves, and whether
one would be suitable for an outside tap to provide warm water to wash
the dog with? I'm thinking I'd connect the hot & cold feeds to the TMV
(inside the house), then set the temp accordingly and chuck a tap on the
end (outside the house).

I've seen some TMVs on ebay for under £25 which sounds reasonable.

Thanks,


As long as you have isolation valves on the H & C feed to the mixer (i.e.
indoors), and put anti syphonic double check valves valves in -line then
this should meet Water by-laws.
I would also put a drain T after the shut off valve so you could drain the
line in winter to prevent freezing - this may also be a by-law requirement
(can't remember)

You can get push fit or compression versions of all of the parts.


i.e.


Hot ---------X---------T----------\
\

O------------|| ||--Tap
/
Cold---------X---------T----------/ wall

X= shut off valve (eg appliance valve)
T= drain T
= Double check valves.
