Can I install it if the wall made of plasterboard (gyprock)?
We and our customers regularly install tanks on gyprock walls. The secret is to locate the “studs”, or wooden posts that are spaced regularly behind the plasterboard. These studs can be located either by using a studfinder machine, or the old fashioned technique of tapping the walls to hear the more solid noise that indicates wood. Then you can mount your brackets directly onto the wood, and so the gyprock itself doesn’t take any load. The brackets on our tanks can be moved sideways along the tanks so that the spacing will match the spacing of the studs in your walls.
