Thermostatic Mixing Valve

[plumb-tech]

Hi guys,

quick question regarding tmv's, I have been asked to install a tmv for a school as the childrens sinks are very hot.

They have 5 sinks in a row, would I need a separate valve for each sink or could I use 1 for all of them?

Thanks

They do tell you on the literature how many litres per minute they can produce, so assuming all 5 may be turned on at once you may end up putting 5 in.

If they're low water using taps you can easily use 3 taps on one TMV.

If they aren't low use, then they should be, especially as it's a school.

Isolators on all taps to reduce flow may help?

Did a school in holidays and put one in per pair

This might help! Was given this by TRITON. Shows the flow rates against KW's and temperature.

Worth tucking away perhaps?

I would be looking at the minimum flow rates of the TMV's first.

We have encountered many problems with TMV's and one of the biggest is the flow rate through water saving taps not being enough to operate the TMV properly.

You may need one on each tap - particularly if its a school and also to cover your backside.
