Water heaters are tasked with heating the water that passes through the pipes to every shower, tub, and sink. These heaters are also supposed to heat water for the washing machine and dishwasher. These units can hold up for a long time, but may begin to cause problems over time. When the heater does not heat water properly all the time, leaks, or makes odd noises, homeowners will know that there is a problem. A water heater that begins to leak could start flooding the house at any moment. A water heater that makes odd sounds could be under pressure and about to burst. In each of these cases, it could be dangerous for the homeowner, and only a licensed Manhattan plumber can fix the problem or replace the water heater altogether.
Much of the plumbing work in populated areas is regulated by government or quasi-government agencies due to the direct impact on the public's health, safety, and welfare. Plumbing installation and repair work on residences and other buildings generally must be done according to plumbing and building codes to protect the inhabitants of the buildings and to ensure safe, quality construction to future buyers. If permits are required for work, plumbing contractors typically secure them from the authorities on behalf of home or building owners.
Plumbers install and repair water, drainage, gas, and other piping systems in homes, businesses, and factories. Plumbers install plumbing fixtures such as bathtubs and toilets, and appliances, such as dishwashers and water heaters. Plumbers also maintain septic systems—the large, underground holding tanks that collect waste from houses that are not connected to a sewer system.
