## Questions & Answers

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.
