Nice piece of kit!

This fitting is good quality. I see previous reviews suggest it might be a bit expensive, but you cannot recreate exactly the core breather overflow for any less effort and cost. The female / female connector is better served with a right-angle bend which is more useful in the kit in my opinion, as the water almost always will need to be directed somewhere.


The kit was very basic and very expensive given the parts bought separately would be significantly cheaper. Does the job but would buy parts myself next time.
