How problematic is doing a mixer shower swap?

[WaterTight]

Or is it as easy as loosen two nuts, remove old shower, re-ptfe protruding threads, put on new nuts and tighten?

It can't be that easy can it?

 

[WaterTight]

Except, I imagine, having just written that, that's it's not ptfe, but, washers, yes, probably.

 

[PlumbBobBob]

yes rubber washers. don't forget to isolate water or you will get wet!

Depends on shower,some have a back plate screwed to the wall,but if it's a bar mixer it should take you all of 2 mins.Just imagine getting 10 to do every day?

If its a bar mixer with 150mm between centres its very easy.

 

[kay-jay]

really easy as said above!

last one i did didn't even need changing! council had sent someone round to do a bit of maintenence and the gobin had switched the hot and cold round in airing cupboard resulting in a shower that never gets hot.

So would this valve:



Be easily replaced by this valve:



Deliberately chosen because it has +/- 5mm centres in case the other one is a bit off.

looks like it should be straight swap. although there will be holes in the tiles where the centre part is fixed to the tiles but a bit of silicone should sort that out.

Ok, cheers.

Just bought it, not fitted it yet. Didn't come with washers. Instructions says to ptfe thread. Is that unusual? I suppose I could buy some washers to fit but maybe MI take precedence?

if you use ptfe just put it on the end of the spindle so that when you put the new mixer on you don't see the ptfe.
