air bubbles in tab water

Featured Replies

I have 2 water pumps, sourcing their water from the same tank, then providing it to one side of the house.

 

The water that comes out of the tabs at one side of the house has millions of those small bubbles inside, which make it look cloudy like if it has lots of calcium inside, but which disappear within seconds.

 

The side that is fed by the other pump doesn't have this symptom.

 

What would be the reason for this, and how to get rid of it?

 

Glasses of tap water, going from cloudy due to air bubbles, to clear, after the water has sat for a few minutes.

Would seem that the pump is drawing air into the system, check all the connections and the pump itself. If the leak is on the suction side then you might not see a water leak but the vacuum when the pump is running can pull air in especially if there are rubber seals on any of the jointings that can be moved under suction then go back into position when the pump stops preventing any water seepage

ok I am going leftfield with my thoughts here.

 

Can I suggest you may have a mircro-mesh screen filter fitted into the tap outlet. they often screw in.

It was a trend in the 90s before everyone was concerened with filtering out crap to have these tap micromeshes.....now the better taps come with them as standard though usually now they go into the flexis.

 

They were "sold" as aerators to make your tap water look fresher/healthier and becasue the mesh is somewhere around 10 microns it sure does create bubbles when under pump pressure.

I have tried already with that tab filter removed, but no change.

 

As for the pump drawing air, I would think that at least during operation, the pump then would run continuously as it can't make pressure.

 

The pump however runs very normal in that the stop time is longer than the run time. It doesn't run at all when tab is closed.

You would need a huge amount of air in the system to make the pump run over for too much longer than normal, try taping the joints one by one and operating the tap to see if you can find a faulty seal. Any type of electrical or gaffer tape will do for this purpose
