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
