Hi, I have a Salamander RHP 100X pump in my airing cupboard, which
pumps how and cold water around the house.

I noticed a damp patch in the bottom of the cupboard the other day, so
emptied and dried it. It looks like water is leaking from the cold
outlet from the pump. The pump is connected to the copper pipes via 4
flexible couplers (hot in & out, cold in & out). These connectors
have a flexible wire mesh sleeve and red plastic push fit at the pipe
end and a black plastic screw fitting at the pump end , somewhat like
a washing machine cold supply connector, and it's the cold outlet
plastic screw fitting which is leaking when the pump is on. Now water
leaks when the pump is not in use and the system can dry out during
this period.

Now my understanding is that these flexible couplers connectors employ
some kind of shut off, so if I disconnect the pump end I don't get
cold water gushing out. Does that sound reasonable ? I noticed they
also have a small white plastic screw near the pipe push fit end and
it looks like it might control an internal valve.

I'm thinking that I need to disconnect the pump end , clean and
examine the inside and perhaps replace an o-ring or washer. the house
has a softener , but there was a period of approx 6 months last year
when it was out of service. I wonder if calcium accumulated, deformed
an O-ring and has now been dissolved.

I did ring Salamander but they just offered me various kits and were
not terribly helpful

Can anyone confirm if my approach is sound ? My fear is I have the
comedy classic of high pressure cold water gushing uncontrollably from
the connector. I also hope this is a cheap repair as this is my second
pump in 8 years .


Thanks

I doubt if there is auto shut-off, but the white plastic screw sounds like a
standard ball valve (sometimes called a service valve, because you use it
for servicing). Should turn a quarter turn, with the slot across the flow it
should isolate (but you may need to tweak the angle to get it completely
isolated). They are sometimes tight and the plastic slots are not very
strong, use a screwdriver which fits well. It probably only turns one way.
