[Belle427]

the pressure relief on my boiler is leaking,its just a small drip at the moment but is there anything i can check out or is it a new part needed?

Leaking prv normally indicates an underlying problem which should be solved first.
Prv can then be changed or cleaned, fairly simple job.

Possibley got a bit of dirt stuck on the seating of the valve causing it to let by a little. You could try opening the prv by turning the red valve top and flushing it through momentarily to remove any possible debris. Then let the valve spring shut by completing the turn and top up the system to 1 bar via the filling loop. If it continues to leak then the seating is damaged and the prv will need to be replaced.
