The plumber has completed the pre-plumbing. The 2 outside taps now have water, Yeah!
The preliminary plumbing for the heat pump hot water has been done, ready for when the hot water system arrive, much later in the build to prevent it from walking away.
The drainage pump has also been connected ready for plumbing onto the future ATU (Aerated Treatment Unit). Modified the 2 stud walls to fit the showers niche and put one the first coat of paint on the front doors to protect them from the weather.
