I wondered if someone could offer some advice regarding installation of a new fast flow 90mm shower waste.
I have a stone resin low profile tray and fast flow waste supplied with the tray by the manufacturer.
On the installation instructions it states to apply a bead of silicone sealant
To the flange before inserting through the tray,
However I'm also wondering if a bead of silicone should be applied
To the underside of the tray also, or will just the rubber gasket
Supplied be sufficient to seal the underside of the tray.
Sorry for sounding thick but just want to ensure best options to ensure completely watertight before covering over and tiling etc
Many thanks
