Plumbing repair & services we provide

We provide our customers with the best services in residential plumbing. Our courteous technicians have been trained to work fast and effective for all the plumbing needs our customers may need.

Drain pipes use gravity to carry wastewater away from fixtures, appliances, and other drain openings. This wastewater is carried out of the house to a municipal sewer system or septic tank. It is important for everyone to take the time to clean their drains regularly because it can prevent clogged drains and backups from happening. When you have a clogged drain or just want your drains cleaned because you’re experiencing some backups, call Diamondback Plumbing and Cooling today. We will have a licensed, bonded, insured and professional technician come to your home to help you with drain cleaning.

Installation of a new gas pipe or repairing an existing pipe can be extremely hazardous because natural gas can be toxic when inhaled in large quantities. It can also be dangerous if there are any potential open flames or sparks nearby. The risks of making a mistake outweigh the costs of hiring a professional. We, at Diamondback Plumbing and Cooling, assure our customers that we are experienced in gas line repair, installation, inspections, and maintenance. We are certified gas line contractors and we use the highest quality and standards for gas line work.

When it comes to leak detection, Diamondback Plumbing and Cooling has the experience and tools to help find leaks fast. Faucet leaks, toilet leaks, and water heater leaks are generally some of the easiest leaks to see and find. Pipes in the walls, underground or in the attic are not as easy to find and we use specialized tools to help us find any potential leaks and problems. If you have noticed a pooling of water or your water bill has jumped up, you may have an undetected leak that you are not aware of. Call our expert team to help you with finding any pipe leaks.

The common problems in the internal water supply systems are the weak supply of pressure and the seepage/leakage of water. The main causes of these problems are usually due to corroded pipes, clogged pipes, age or a fracture in the line. We can fix any type of plumbing leak you may have. We have been serving Maricopa County for over 20 years providing reliable plumbing leak repair services at an affordable price.

When doing a kitchen renovation, the plumbing plays an important role as to where things should go. For instance, you cannot place a sink just anywhere in the kitchen; there must be a water pipe nearby that you can tap for the faucet, and there should also be a drain pipe for the sink. We can help you with kitchen renovations, remodels and make sure all your plumbing needs are met with your new kitchen. If you need your kitchen plumbing repaired or drain cleaning, Diamondback Plumbing and Cooling is here for you 24 hours a day, 7 days a week.

Typically, water heaters operate off a 240-volt power line, which can deliver a fatal shock if handled by untrained hands, especially if the unit is spraying, flooding or constantly leaking water. Hiring an unlicensed handyman or taking it as a DIY project would cause more harm than good. We will provide you with expert solutions to repair or replace your water heater in Phoenix. You can rest easy knowing our certified team installed your water heater to code at an honest price.

Softening water is the process of removing the minerals in the city water that is the cause of hard water. In the Phoenix water, there are a lot of minerals in the water causing the water to be hard and can damage your plumbing, appliances, and fixtures. These minerals or ions contain high amounts of calcium and magnesium. A water softener is designed to remove these minerals/ions, softening the water and providing a better functioning plumbing system in your home. Learn more about our water softeners here.

Garbage disposal units break down kitchen scraps so they can travel through the drainpipe without clogging it. Since most of us do not have the time or skills needed to fix a complicated device like a garbage disposal on our own, it’s good to know that Diamondback Plumbing and Cooling is here to fix or replace your garbage disposal.

The water pressure regulator is a valve that reduces the water pressure that comes into a home from the main water line. The regulator is a key link in a home’s overall safety. At some point, all plumbing fixtures, valves, and water pressure regulators will go bad. If water hammering and other inconsistencies in the water pressure are seen, it may be an indicator that the water pressure regulator is not working properly, and if that happens, Diamondback Plumbing and Cooling is here to fix it.

If a residence is not connected to the Phoenix sewer system, it will use a septic tank to store the raw sewage that the household produces. Solids get to the bottom of the tank and are partially decomposed by bacterial metabolism in the sludge. Over a period of time, a septic system can develop problems that can impact the whole plumbing system. If the septic system is not serviced and emptied regularly, not only will it cause significant damage, but it also risks the replacement of expensive waste system devices. We provide septic services for cleaning, repairing and replacing septic tanks. Learn more about our septic services here.
