The alarm bells were ringing when during the early hours of Wednesday Morning the water pump kicked in!
For those not familiar with the on board water system, water is pumped from a holding tank, and raised to a system pressure by an automatic pump. When the system pressure drops, the pump kicks in, and restores the system pressure. The sound of the pump is normal, some say reassuring, when water is drawn off through the various taps, shower etc…
However the sound of the pump running, for even a few seconds, when all outlets are closed is an indication of a system leak!
I lay in bed working out the possible reasons…..then went back to sleep dismissing the incident as a one off…..
Thursday evening, while settling in front of the TV, the pump kicked in again for about 4 seconds! I decided there and then to investigate in the morning….water outside a boat is normal, water inside a boat is dangerous…
After checking for signs of a leak, beginning at the storage tank, there only remained the bathroom..:(
There is a small holding waste water tank behind a panel. Waste from the wash basin, kitchen sink and shower are all collected there before being discharged by the ‘Whale Gulper’ pump. There were signs of water leakage in the area so on with the marigolds and out with the tank to reveal a damp patch below the cold feed pipe to the shower….yes here was the site of the pressure lose. A loose connection just needed a slight tighten …..
Now replacing the holding tank revealed that connections had been leaking and water was under the floor of the bathroom. I used the ‘Whale Gulper’ pump to empty out the water, and mop up with towels. Plastic pipes had hardened with age and split, replaced with new pipes before refitting the tank.
So far so good, no more unusual pump activity…….
The moral, do not ignore unusual noises on board a narrow boat!
