Nature pure QC water filter (basic) fit

I decided to upgrade my nature pure water filter to the latest QC (quick change) model.

Fitting is so simple, just cut the cold feed to the bathroom mixer and fit the threaded connectors

The wall of my toilet is hollow board so I mounted the QC head unit onto a solid piece of board to then fix to the wall below the sink.

The water through flow is much faster than the old model

The new model is so much easier to winterize or just change the filter.
When unscrewing the cartridge a valve shuts off the water. You then fit the black plastic blank plug in place of the filter to allow water to flow through the cold pipe without the filter so you can now flush or drain any water.
