Key takeaways
- Hunter Water aims to supply at least 200 kPa at the connection to its main for standard connections.
- A quick check: if a 10 litre bucket takes 30 seconds or longer to fill at the tap nearest the meter, pressure may be low.
- Low pressure at only some taps points to your own plumbing, often blocked tap filters, a failing valve or old pipes.
- High pressure is hard on everything it feeds. Banging pipes, a dripping relief valve and burst hoses are the signs, and a pressure reduction valve is the usual fix.
