The water coming from the mixer tap in my bathroom is now just a trickle, also the toilet cistern is filling up very slowly. I had a new bathroom suite installed six months ago, everything was working fine until quite recently. I have checked the valves from the water tank in the roofspace and both are in the open position.

if they are both fed from a tank in the loft.
stick the hose down the tank inlet with the mixer tap on cold it will blow the airlock through.

unless you have a blockage in the pipe.
