Bristan mixer - scalding or freezing. Botched installation?

[Matt Lord]

Hi folks.

So I'm thinking the hot and cold feeds have been plumbed in the wrong way round on this Bristan mixer. (Combi boiler installation.) I'm no plumber, but as I understand it, hot should go in on the left (i.e. the bottom feed in the photos) and cold in on the right.

If that's the case, the feed in the photos at the top should be cold, and the feed on the bottom should be hot, no?

Currently, the one at the top is hot, and the one at the bottom is cold.

Is there an easy way of rectifying this? Or because of the way it's been fixed at a 90 degree angle, do I need to call a plumber to do a spot of re-plumbing?

Thanks for any thoughts.

Your inlet elbows will swivel through 180 degrees. You can then swap the plug to the top(lhs) outlet with the fitting on the bottom (rhs) outlet. Re-fit the valve turned through 180. This is assuming that whoever installed it has not already done that and that reversed h & c is indeed the cause of the problem.

 

[Daveydub]

Think that you will find H & C stamped on the back to confirm orientation.

Simple as Davey says. Remove the valve, rotate 180 degrees. Job done.

Thanks chaps. Appreciated.
One thing - which part is the 'plug' Davey is referring to?

The plug is on the left hand middle of the shower valve. You need to remove this plug in order to reconnect the middle pipe ( the one that go to shower head ) when you turn the valve over 180 degrees. Then when done, refit plug onto the one where shower head pipe used to connected.

Your picture does not show it well but it looks like a screwdriver slot on the left hand side though it may well be a nut shaped plug.
This is just an alternative connection point as shower offers option of top or bottom outlet.
This is the fitting instructions in case that helps.

Ah, got it. Great stuff folks. Thanks.
Just need to find those stopcocks...

 

[Daveydub]

Turning off at your main stop tap should do it (combi boiler).
Would be a good idea to clean the filters while you have it off the wall.

 

[Matt Lord]

Good idea. Where did I put the vinegar...

 

[Matt Lord]

Just to say we now have a great shower, thanks to you chaps. Good job!
