We have been notified by the NYC DEP that one of our water meters will be replaced soon. The letter states that the water meters have internal parts that can wear out and may under report water usage. They also reserve the right to back bill us for up to 4 years based on the new readings if there is a change in usage reported with the new meter. (No mention of a credit if it’s less). Our concern is that the last time they changed one of our meters, the piping was under sized – a 2” meter had a pipe which measured only 1.9” OD, which might give us 1.75” of water flow, effectively reducing water pressure in the building. Failure to permit access can result in penalties. Building agent has been unable to get any response from DEP or the contractor regarding the new meter pipe sizing/flow etc. Any ideas?
