So, after losing hot water pressure to my kitchen and 2nd shower I decided to look into why and all signs point to the strainer being blocked.
After checking out the Installation and Servicing Instructions and getting a plumbing friendly acquaintance around (ie, someone who has already done the job himself) we've come to a standstill. The booklet says to turn off the cold water supply, boiler and immersion heaters and then run the lowest hot water tap dry so as to de-pressurise the system. This has been done - ran hot and cold water dry on all taps. Then it's saying to Unscrew the cap from the Pressure Reducing Valve to access the strainer mesh. This is the bit we're both stumbling on.
Whilst the cap does indeed rotate there appears to be some sort of safety lock on it as it just clicks (like a tamper-proof medicine bottle) when turned. There is an arrow pointing up on the side and it appears that the very top of the cap appears to turn independently but there isn't another arrow to line up and it doesn't seem to move more than 1cm in either direction c/w or anti-c/w.
If only I could get this cap off and clean the strainer. Can anyone help?
Thanks for reading.
