Hi Would like to know how to not get ripped off by plumber. Looking to replace hot water heater with heat pump.
Is it as simple as getting to state on the quote the job description in detail? If so what are important to get the plumber to put in the job description?
I remember reading a bit online, is rcbo and switchboard upgrade required and also tempering valve , non return valve, pressure limiting valve, ? Anything else?
Also any website recommendation to read so I can get a better understanding
Thanks
