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

Well it works, so far, but this is the third of these switches in 8 years I have had to replace due to the same failure that saw the pump running constantly. I just wish they upped the quality even if it cost more as it is located in a hard to reach position. Best not to make this switch in China perhaps.
