Regards,
Xylem.

**Q: How long are the lead wires**
A: Hello,

Regards,
Rule.

**Q: I have an older version of this that has a turn able knob on the side.  Any idea what this is used for?**
A: Hello,
The older float switch has a knob on the side so you can rotate and lift up the float inside to test the system.
Regards,
Xylem.

**Q: Is the hole spacing (and/or general dimensions) the same as on the older mercury switch rule-a-matic plus model?**
A: Hello Matthew,
The new float switch is slightly different from the old mercury float switch.
The mercury switch has a different hole pattern so you will only be able to use one of the holes from the old switch.
Regards,
Xylem.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great!!
*by C***E on 16 August 2026*

Exactly what I wanted and exactly what I order!!

### ⭐⭐⭐⭐⭐ Good quality
*by D***N on 9 August 2024*

Works as it should

### ⭐⭐⭐⭐⭐ Replacement required
*by K***E on 7 September 2023*

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
