Q. Can one use a ‘Foul Water Pump Controller’ during Shabbos? What is Horav Shlomo Miller’s Shlit’a opinion?
A. As described by the company; “The flushing of a toilet or using water in places where the foul water is collected in a Sump Tank, often installed in basement and ground floor applications, results in the water lifting a float switch and activating the foul water pump.
This action is prohibited during Shabbat. ShabbatSmart Sump Pump controller, activates the pump on Shabbat at pre-set time intervals and, will stop the operation if the water level drops. This way, the user’s action does not trigger any prohibited actions on Shabbat”
The above pump system is certified as Kosher LeMehadrin by HoRav Shraga Feivel Zimmerman - Rov and Av Beis Din of Kehillas - Federation Beis Din, London.
Horav Shlomo Miller’s Shlit’a opinion is similar.
