hot or cold but not both

This question is regarding Mira Excel (1990-96) Cartridge - 903.33

Shower was producing poor pressurre so having checked inlet supply OK - I bought a new 903.33cartridge.

When fitted I found I could not get hot water but cold only pressure good. To test - I reversed the cartridge and found I was getting good pressurre hot but no cold (which I should expect - just wanted to be sure that both hot and cold supply at good pressure was getting through. Shower fitted in 200/2001. I was running with normal low pressurre - prior to the problems but amn told that our pressure is quite high - should I try high pressurre setting on cartridge??

Failing this - any suggestions??

I would give thepipe work a flush out in the first instance  Strip out thecartridge and make sure that it is set for low pressure. When it is out givethe pipe work a flush out. This will take two! If your valve isrecessed pack an old poly bag round the valve to divert the water into yourBath / shower tray then turn the hot and cold valves on one at a time and allowthe water to flush through for about 15>20 seconds. The person who ishelping you should watch that the water is not going anywhere that is going todo any damage also they should watch that the amount of water coming from thehot and cold they should be roughly the same, if it is not then you have aproblem with the plumbing.  When refitting thecartridge make sure that the filters are clear before refitting. If this doesn’t fixit then get back to us
