Re: How to Remove Air from Fresh Water Lines

Sometimes itís small things that cause big problems. I recently had a fresh water flow problem and was convinced it was air. It turned out to be a clogged filter (upstream of the pump) and clogged screens in the faucet tips themselves. 5 minutes and an old toothbrush solved it. I assume it was mineral build up.

I can only assume that the lines are full of air that is stopping the water coming through. How can these air bubbles be removed or bled out of the lines so I can pump water again?
Hi. Use your foot pump to the dinghy connect it to the hose next to the pump and press air backwards into the tank. See what happens. Jon

How to Remove Air from Fresh Water Lines (Version 2)
Firstly, thanks so much to all those who responded my dilemma. I have followed the advice received. We focused on the link between the tank and the new water pump, firstly by blowing down the pipe into the tank resulting in blowing bubbles in the tank water. When you suck up the pipe we only get air. We have since discovered that on the tap end of the pump there are three Suction Control Valves that enable you to select which of the yachtís two water tanks you wish to draw water from. We have tried setting the valves into various positions and still canít pump water. I think we now have a larger problem than I originally thought so have decided itís time to call in the professionals. I sincerely thank everybody for their constructive suggestions to date.

Clearly you have an air leak into the system between the tank and the pump. It seems to be fairly small or you wouldn't be able to blow bubbles into the tank. Again, I would check the o-ring at the filter, tighten hose clamps throughout the system, etc. Or, as I suggested earlier, replace all the hoses, fittings, the strainer/filter, etc. If the system has been sitting for four years, growing mold, etc. maybe you don't want to be drawing your drinking water through it.
