Water Pump on its Way Out?

Recently our water pump has started making different noises from usual: possibly a bit more gurgly and sometimes seems to run on sightly more than expected after the tap is closed. Although we have had the boat for 11 years, I have no idea if we have an accumulator. There are two mysterious boxes on the hull-side under each side of the pullman dinnette. Should we be buying a new pump at the earliest opportunity? We've had three pumps whist we've had the boat so at that rate we we might be due another one.

The "gurgly" sounds point to a problem between the water tank and the pump; there may be a poor connection that is allowing the pump to draw air into the pipe as it is sucking water from the tank. This will also account for the pump running on more than usual after turning off a tap; this is due to air in the system which needs compressing (incidentally acting like an accumulator). It is also possible that your diagnosis is correct and the pump is on the way out.
It might be worth looking to see if there is an accumulator as although many pumps will work without it can take some of the shock loading off the pump valves. This will prolong the life of the pump and stop short cycling when the pump runs for a very short time to maintain pressure.

Nice to know my diagnosis was correct. Thanks

Turned out to be a leak on the water filter which just required a minute tightening of the the filter cap.
