Re: Slow filling cistern

The first thing is what type of ballvalve are you looking at, if it the normal type with a ball at the end, after turning the water off remove the valve and at the end that screws to the cistern you will find a plastic insert they come in two types high pressure and low pressure. The first thing is to check a high pressure insert has not been fitted to a low pressure system ie the cistern is fed from a F&E tank in the loft (low pressure) the other thing to check for is the insert has not been blocked with small stones or scale. The problem is that when you purchase a new ball valve it is fitted with the high-pressure insert normaly white, the low pressure one are red. But just to confuse you I carry three sorts and they are all white.

Hope this all makes sense, donââ‚Âà ‚¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚¢t think you will have a problem with scaled pipes as this a problem for hot water pipes and as far as I know Letchworth area has the hardest water in the UK 21/22 deg Clark
