Haw. Code R. § 15-319-61
Where it has been determined that noises emanating from a consumer's premises are caused by plumbing fixtures or other equipment attached to water pipes and such noises are being transmitted through the water pipes and causing annoyance to other consumers, the corporation may issue a notice in writing to the offending consumer, the owner of such premises, or the owner's agent, giving the consumer thirty days within which to correct or to remove the cause of the complaint. Failure on the part of such consumer, owner, or person responsible to correct or remove the cause of the noise will be sufficient reason for discontinuance of water service to the consumer until such time as the condition complained of has been remedied.
