how would I know if it's worth investing in one of those?
You may already have one needing to be charged, have a look near the water pump for something along these lines
I would have thought that most electric pumped water systems on boats were equipped with accumulators. It's simply a container with air in it, which is compressed by the water pressure. It means that, for example, if you want only a cupfull of water or thereby, when you open the tap, you'll get your cupfull without the pump coming on at all. It saves the pump going on and off so frequently. Are you sure that you don't already have one in your system? If you do, it may need attention. Some are simply a small vessel, theoretically full of air, with the pressurised water connected at the bottom. Over time, the air is consumed, the chamber fills with water, and needs to be drained. Some have a rubber bladder within the chamber, which should be charged with air. IIRC mine has to be charged to about 13psi. As to whether it's a worthwhile investment, only you can decide. If you don't already have one, I think they might be between £30 and £50.
Possibly
That's really helpful. ?
Most pumps benefit from an accumulator. It reduces the stop/starts over its lifetime. Lots of these devices measure the useable life in stop/starts so you effectively increase the life of the pump/motor
If you are woken up by the sound of someone filling a glass of water, or washing their hands, with the resulting pump noise, in the middle of the night.
