Unusual plumbing failure on filter supply
The last two quarters I’ve had letters from my water supplier saying we are using over double the amount of water as similar properties in the area; stating they think there’s a leak. So I did the usual checks and couldn’t find anything other than a trickling toilet.
This morning I’ve done an extensive service in the filtration including unwrapping all the insulation I have on it year round. Result being I’ve found a big leak on the supply pipe to the drum filter.
Took it all apart and look ok until I found this when I took apart the speedfit fitting…

I think that’s water erosion, from the speedfit fitting. I’ve seen electrical arc damage on copper components in HV situations, and it’s not that dissimilar to my eyes.
On further inspection the pipe end going into the speedfit fitting was ever so slightly flattened - to the point I could only see it in certain light from a specific angle.
Anyone else ever noticed this?

That's water erosion due the there being no clamp, such as a Jubilee clip, on the hose which has allowed a small but high powered jet of water to leak.

There was a clamp - you can see the imprint on the hose. Note I cut the hose back this morning by roughly 5/6mm to see what was going on - you can see the ring around the pipe where I did this.

Even if there was a clamp, the scenario is still valid Dave, a tiny leak where the hose should have been tightly clamped against the pipe will have caused the erosion as you can see from the water tracks it has left behind.

Still seems very strange that the hose didn’t erode and the copper did….
Plus I always compress an olive on the pipes so that the hose seals better and prevents the clamped hose popping off.

Copper is soluble in water when it can't form an insoluble copper oxide film on its surface (which is why copper domestic plumbing doesn't dissolve) but, under high pressure if there was any tiny leak, it would continually jet wash the copper oxide away and allow the water to dissolve the copper

Drawing new diagrams of bacteria and parasites for my latest Bacteriology course is tedious and every so often I need a break so I thought I'd knock out a quick and dirty diagram of what I tried to explain in my earlier posts in case anyone was unsure.
