I saw your segment on Youtube regarding the main drain. I’m renovating my pool(tiles and plaster). I understand that it is up to code to install another drain at the bottom of the pool. I was also told by a pool company that installing a SVRS Anti-Entrapment switch to the pump will serve the same purpose. Is that correct? and Is it ok to shut off the main drain while the pool is open for the season?

Any information will be greatly appreciated.
