we have a centrally mounted mixer tap with a shower attachment on our bath.
The side of the bath which has the tap fitting is against an outside wall.
The shower/tap mechanism is a sleeve beneath the shower hose, pull up for
shower, push down for tap water. However, this mechanism has stopped
working, and now water will come out of the shower, but not out of the tap
unless the water flow is reduced to a trickle. The only thing we have
recently done is to change the shower hose, re-drill the riser bar mounting
holes and dre-do the grouting. Could something gritty falling into the
shower hose hole cause this problem? How can we fix it please??
This may be the problem. I replaced an en-suite for a neighbour last year.
They provided all the components. They did not want to change the shower
valve as it "is a good shower". They did change the hose and head though.
After the refurb the man said the shower wasn't as good as before and had I
left an isolation valve part closed etc. As I never isolated the shower
valve I new this wasn't the case. I took my shower hose and head over to
their house as my shower is the same and I still had the original bits and
Hey Presto shower back to normal. I don't know why though but probably down
to flow rates, back pressure, etc. They have since bought a new hose and
head from the original shower manufacturer. Do you still have the old hose
and head or could you borrow one from a neighbour to try?
The usual problem with this type of unit is scale/dirt in the diverter
Also reduced/increased back pressure form either the hose/head or the
spout outlet can make them want to only operate one way, or jump
uncontrollably from/to the shower or bath setting when /it/ wants to.
The parts do come apart for cleaning /replacing O rings etc.
Also the flow straightener unscrews from the spout and it may have debris
