We've had issues for ages now with our water supply. The mains supply

The worst problem is when more than one hot tap is opened and demand
is higher around the house. What happens is that fairly large
particles, which I can only describe as being similar in appearance to
snots (no joke!) flow out with the water. I've been wondering for a
good while as to what the hell this stuff can be. You don't really see
it with just one tap opened, or demand being lower, but its an
unpleasant thing to have in your supply right?

I've talked to plumbers, they don't want to know really (because I
presume they have no clue how such crap could form in the hot water
cylinder). Live in Dublin btw, and never seen this in any house but
mine. Would appreciate input, cheers.

Do you have a header tank? If so, have a look in it.

Have dancing shoes, will ceilidh.

There is some sediment on the bottom of the tank, I clean and
disinfect it every year. This problem with the hot tap has always been
there though..

Is it a private supply?
we had something similar a few years ago, lots of sediment in the
header tank - since removed for new system - I suspect the snots were
hot water dwelling "fungi" or equivalent lurking in the hot water
cylinder.

We're on a mains water supply, not a private system. It does seem to
be some sort of bacterial growth in the hot cylinder, if it were
isolated to a pipe length, it would be flushed out eventually. It
comes from any hot tap when demand is high in the house,

*I just wish I could find out how to get it sorted. We've had our
current hot water cylinder for almost four years, and I know it
occurred in the previous one too (that cylinder ended up leaking, I
wonder if this stuff is corrosive too).

bacterial & fungal are easy to sort, put a bottle of bleach in the
header tank, leave it there for a bit, then draw enough water for it
to enter the cylinder. Flush out through all the taps later. At least
you'd eliminate one major possibility that way.
