REPLACEMENT/REPAIR CERAMIC DISC WATER FLOW CERAMIC DISC CARTRIDGE:

Symptoms: Does your Bath Tap or Shower Valve drip? Are you is a hard water area like 60-65% of the UK? Solution: Simply change the Ceramic Disc Cartridge, not the whole tap or shower! 
 

Principally made from brass, this Ceramic Disc Cartridge is suitable for various Mixer taps and shower valves.  This is the left side mechanism component part as you look at the front of the Mixer Taps/Shower.

To install it with a Bath Mixer Tap or Torpedo style Bar Shower valves, all you have to do is prise off the end cap, remove the grub screw inside, then undo the 'nut' shaped section of the cartridge. Always ensure your water is off when fitting!!

The Dimensions are:  Total Length of Cartridge = 48mm. It is a standard 1/2"BSP size thread (measures 3/4" diameter where it fits into the taps/valve body). This 'inside' section that goes into the Taps/Shower is approx 22mm long. The diameter of the main housing that fits inside the mixer body is some 17.8mm and it is approx 13mm long (excluding the threads). There are 20 splines (teeth) and the diameter of them is 7.5mm.

Please check the image above and the dimensions before purchasing to ensure a good match and carefully compare to your one before installing. Please note this is NOT a Thermostatic valve.
