kitchen mixer tap check valve

[Mgrant]

Should kitchen sink mixer tap have a check valve on it if its mains cold and tank fed hot water?

 

[Mgrant]

Is it just the cold side if there needed? Can imagine the tank feed hot would struggle to flow though a check valve

 

[Mgrant]

Do most mixer taps mix outside the tap.body so dont need a check valve?

 

[buckley plumb]

Most come out of the spout in separate nozzles

 

[Mgrant]

So no che k valve required?

Check instructions

 

[Mgrant]

Instructions dont say anything but its a single spouted tap so the water mixes in the tap body

As per MI'S

If your unsure and is tank hot and mains cold put one on the hot just incase

Thanks would a check valve on the hot reduce the hot pressure/flow even more. Is already quite poor.

Yes slightly it's either that or find a new separate tap

And fitting without is a no go? The one that's in at moment mixes in the body I think and has no check valves on the pipework

Fit it without and see where water Comes out of spout if different place then it's OK if not then add check valve. I don't think the plumbing police will arrest you
