Well I have been for a lesson in using my pressure washer and found a guick release connector for the trigger gun would be a better solution than all that screwing and unscrewing.
You would think two males and one QR in stainless steel would be easy to scource but Im still at it four days later.
The lesson also demonstrated the effectiveness of harvested and filtered rainwater and completely killed off any idea of a resin filter and expensive refills.
Deciding on a suitable tank layout and where to install it is my next challenge.
Sliding slower, but still sliding -> -> -> -> -> ->
