shower not working

i recently moved house and took my shower valve with me. i fitted it exactly the same way with pump, and salamander valve on top of my cylinder. when i turn it on the hot will only come on for a small while then go off. it works fine through the cold. i have fitted a prv on the cold so they both have equal pressures. the pump works fine as i tested it. i was just wondering if anyone had any ideas

Strip out the cartridge.

 

When it is out give the pipe work a flush out.

 

This will take two!

 

If your valve is recessed pack an old poly bag round the valve to divert the water into your Bath / shower tray then turn the hot and cold valves on one at a time and allow the water to flush through for about 15>20 seconds.

 

The person who is helping you should watch that the water is not going anywhere that is going to do any damage. Also they should watch that the amount of water coming from the hot and cold they should be roughly the same.
