worcester greenstar cdi flow unit

[giarc00007]

went to above boiler and found the plastic flow unit had a pin hole. just wondered if you guys had any heads up regarding changing it. do i need to take out hydraulic block. Also ive got hardly any access underneath boiler either.

Change the hydro block as well while you're at it, only an extra 12/14 quid and saves you going back WHEN it pinholes as well

I've got a CDI in my place that's like Triggers broom, not a lot of original parts left on it

Easy enough as long as you like spanner rash
I always seem to leave bits of me on the back of the plate
