This question is regarding Mira Excel/Select Thermostatic Cartridge - 903.33

Mira Excel

I have replaced the cartridge on my mixer shower because the old one (410.12) was dripping. The flow rate on the new one (903.33) is acceptably low and varies from just OK when you start a shower and then gradually gets less. I have two Excel Mira showers - both are gravity fed directly from the hot and cold water cylinder/tank respectively.

I have checked the pressure setting on the cartridges and this is as it was on the old one (low pressure). I have also checked the filters and they are aslo clear.

Any ideas what is going on?

Check that the shiower hose is not kinked or collapsed internally and the shower head is clear. Easy way to check is to remove hose from valve and check flow.
