Fitting a new shower tray. This is probably a dumb question but that last shower leaked.
The waste I bought from plumb world
Am I right in thinking that I fit the waste to the shower tray by putting plumbers mate underneath the flange, drop it ithrough the hole in the tray and secure it with the washer and the nut from underneath?
Or is it possible that the washer goes between the flange and the tray (no plumbers mate) and just the plastic nut underneath?
Advice would be most welcome.
