Plumbers paste on immersion heater compression valves

View the thread, titled "Plumbers paste on immersion heater compression valves" which is posted in UK Plumbers Forums on UK Plumbers Forums.

So did a job for a friend yesterday and made (i hope) a small muckup....

Installed a unvented heatrae sadia multipoint 15 but i used plumbers paste on all my compression elbows about 10 of them i only put it on the male threads.

The instructions state that it should not be used as it may impair the valves....

What do i do?
-take it to pieces then clean everything and install again?
-leave it?

Is the worse that can happen buying new temperature/presure valves or is there more serious things that can happen?
 
Thanks for the answers! only used a little and and only on the male thread... upon checking one there was little to no residue on the inside of the pipe.
The water is not connected yet so this would be the ideal time to start over.
would i be better of taping the male thread with ptfe after cleaning everything?

Are you talking about the compression elbows or male irons into the heater, PRV, expansion vessel etc?
 
Bit of a worry here Johnny although not notifiable to building control these water heaters need to be fitted by a trained installer , the termination of the safety devices needs to be be installed to comply with the water regulations and they need to be commissioned and tested are you qualified ??
