2003 Trident - Water Pump

As far as I'm aware, the pump on a Trooper or Trident is always in the same place - under a false floor in one of the cupboards to the left of the bed. You'll know which, because typically only one of them has a false floor - though it can sometimes need a bit of effort to lift (I had to use a car jack on our Trooper to press the side walls apart a tiny bit!).

The problem is ~probably~ due to an airlock, but there could also be frost damage to the pump if a small amount of water stayed in it over winter. It's not unknown for the filter - which is typically attached to the side of the pump - to split. If that happens, it can suck air in (it's on the inlet side to the pump) and therefore it won't prime itself.

Do you mean that it's noisy by Shurflo standards, or just noisy? Because IMO Shurflo pumps are - by their nature - noisier than most. And if they are noisy, that is more than likely because a previous owner or maintainer has pulled the pump too hard down onto its mounts. In my experience, the first thing you will notice as a Shurflo gets old is that it stops being able to prime itself over any great vertical distance.

It may help, that's true. But please do check the pump mounts. If mounted correctly they are intended to only just be tightened to stop movement. After that, the more they are tightened, the more sound transfers to whatever they are mounted on.
