Hi all,
since a few days I notice the hot water pressure is reducing by the day and is now a little more than a trickle. We’re on a low pressure system with wet-back. The house was  a  new build and plumbing is now 6 yrs. old.
I’m wondering if it could be the tempering valve as there was a clicking noise right from the beginning? There is also a gurgling sound in the pipes by the HWC which doesn’t sound normal. Unfortunately, getting a plumber  out here is very difficult (and expensive)  as we’re quite remote. (Karamea area) Any advice is much appreciated! Thanks in advance

thanks for your reply, integrated, - but if it's the wrong temp valve it would have been that low pressure from the beginning?!

there is a filter between the header tank (on a tank stand outside) and the house entry, I've cleaned that one out, but doesn't seem to have caused the problem.
