Before calling anyone in Hamilton, check whether every tap is weak or just one. On housing this recent a house-wide drop more often turns out to be the pressure-reducing valve or the meter than the pipe itself. Normal supply is 45–80 psi and under 40 psi is low — how to test it in a minute. Whole house is a supply problem worth a call; one tap is usually a five-minute job you can do yourself.
