"This product does not inspire a huge comment! It fitted very easily and was a reasonable price. Its reliability will of course be decided in time but there is nothing to suggest it will not prove reliable."
"Brought two, one for central heating and one for cld water tank. Being sligtly cautious I submerged them overnight. One leaked like a sieve the other was ok. Screwfix accepte dreturn but could have been messy if fitted even with a good overflow!"
"Bought this as a replacement for a different float that had been professionally fitted three years ago, which had filled with water and caused the tank to overfill. The new float was filling with water after a week. I checked it by submerging the float completely in warm water and a stream of bubbles appeared. My advice would be to buy two or three, check them as I did in water, take back any that leak or those that you don't use. Or buy a different brand from somewhere else because Screwfix sell only this one."
"Easy to install, worked fine for the first couple of months. However, eventually one day somehow water managed to enter the ball (same problem as the first reviewer). Cannot be emptied, therefore worthless and unusable. Such a shame, would not recommend, as it left our house dripping with water!"
"I fitted this ball float with a new peglar valve to my central heating tank. I was woken up at midnight with the overflow pouring out full blast outside my bedroom window. I had to turn off the water at the stop tap. Next day up in the loft after draining the tank, I suspected the valve at first but on refilling the tank I discovered the new ball was full of water. the cost of returning the ball would cost more than the refund on the duff ball so I fitted the old ball. I am only pleased it was not fitted to a customers house, I would have looked a right twit"
