Cast Iron and Copper drain pipes
 STP Plumbing specializes in the installation and repair of piping including cast iron and copper drain pipes. Though this type of piping has been around for over 100 years and often replaced by schedule 40 PVC, cast iron and copper drain pipes allow water to flow through them much more quietly than their more modern counterparts.

Copper Water Pipes
 Galvanized plated steel piping rusts and causes a cycle multiple costly repairs to restore the optimal function of showers, tubs and sinks. A great way to stop the galvanized steel cycle is to re-pipe your home using copper water pipes. A re-pipe eliminates low water pressure giving you a great shower. The image illustrates the problems with galvanized steel pipes.

Main Sewer and Water Pipe 
Over time, pipes under a house or building rust from the ground water and water drainage. This causes a variety of sewer and water main problems. STP Plumbing has over 30 years of experience with these types of problems and offers customized solutions.

Overhead Sewer System 
It’s quite common to experience a city sewer back up during a heavy rain; an overhead sewer conversion prevents flooding in this situation. This protects your home from sustaining costly water damage.

Valves are crucial to the operation of plumbing in the home; when one stops working properly, it needs to be replaced quickly. In order to help your valves live a long life, remember to exercise them routinely. Mineral build up within the moving pieces of the valve is the most common cause of valve replacement. STP Plumbing installs, repairs and replaces all valves.
Pictured is a globe valve. Experiencing a sudden water flow decrease? This valve could be to blame. It uses a rubber washer, which decreases the volume of water flow by half. If you notice a decrease in water flow with more than one fixture running you may have this type of valve, and replacement may be necessary to optimize water flow.

Backflow Preventers
 Backflow preventers or cross connection valves are used to protect water supplies from contamination or pollution. STP Plumbing installs, certifies and repairs all backflow preventers including:

  • Backflow Prevention for Toilet
