    • Replaced my flow cartridges on trevi therm, shower struggled to turn off and would come on itself.
      Original was corroded, leaking and stiff.
      The difference is phenomenal, next day delivery and they sorted the problem, turn on and off so much easier and only took 20 mins to fix.

    • Good product

      Martyn Busson

    • Easy to change and fits existing mk1 trevi boost. Doesn’t have the mechanical stops of the original so remains to be seen if it lasts as long (26 yrs for original)

    • Got these to replace the originals which were very difficult to take out the new ones are far better in design so so the socket grips much better than the older model 21mm if i remember correctly

    • My flow control initially turns water on to the shower then fails to respond to any further increase in flow despite rotating the control.
      After about 20 seconds the flow reduces and can only be (temporarily) increased by turning the temperature control up.
      The gears and spindle are not worn, so do I need to replace the Trevi 1/2 '' flow cartridges ?

      Hello, if you remove the spindle and cogs, turn the valves carefully with a pair of pliers, do they work?, if they do, and the flow still dimisnishes, you may have a supply/blocked filters problem on the temp cartridge.

    • Hi,
      When my Trevi boost shower is turned off, it still drips water from the shower head. Is is likely to be the flow cartridge that needs replacing or the booster cartridge? When working the power flow and water temperature is fine.
      Thanks

      Hello, definately the flow cartridges, there are tweo in each shower, A952501 , it may also be the gearbox A963067
