Dripping Shower Megaflow Recharge for Noob

[Benny130]

Hi and thanks is advance.

I have been told that my dripping shower may be resolved by recharging my megaflow.

The first step is to shut off cold water to megaflow. Where will I find that?

Pics of system and instructions below

Thanks

if there isnt a stop tap in your cupboard look under your kitchen sink and just use your mains stop cock

Ok done that, thanks for the reply. Just follwing other steps and hopefully it will all be good.

Is it me or does it look like the PRV has a bend in the pipe back towards the wall? Ok it makes the pipe work look neater but it should not be done this way.

The bend is OK , but I wonder where the pressure reducing valve is

 

[scoobydo123]

I thought it had to drop straight down for a prescribed distance without any bends or is this after the tundish (cant remember ).

600mm max from T+P to first bend of D1.

300mm vertical minimum before any bend after the
tundish on D2

Ok the reset of the bubble in the mega flow doesnt seem to have helped the drip. Can anyone give me any ideas of what it could be. Its a thermostatic shower btw

You need a new shower cartridge.

Is that easy enough to do? Is it just a case of replacing?

 

[HERTS P&D]

Yes, quite easy to do. Turn off water supply to shower (hot and cold) Remove front cover, should pull off or be fixed with a centre screw. Then depending on what type of shower, it will be either have 4 screws, one in each corner or a large nut to undo. Remove, replace cartridge, replace cover and turn on water supply to check for leaks.

When you buy the cartridge, it will be come will instructings. Or you can down load the instructions
