What to ask before you hire
General questions worth asking any supplier. They are not about JAS Civils in particular.
Rainwater harvesting
- How much water can my roof collect in an average year here, and what tank size does that suit?
- Are a leaf screen and a first-flush diverter included?
- Will the water be used for drinking, and if so, what treatment does it need?
Any plumbing work
- Will a PIRB-registered licensed plumber do or sign off the work, and will you issue a plumbing certificate of compliance?
- Is the quote written, and does it list labour, materials and call-out fees separately?
