Replacement required
I had to buy this as a replacement. The old unit would rise on the water level and as the float dropped it would not turn off the pump. If they were to make the float valve easy access then regularly maintenance could have been carried out to clear scale build up on float switch . Easy to fit . Comes with a lengthy power lead
