"Harts dispatch kept me updated on the status of the plumbers arrival. We called for two issues and of course the mystery noise stopped the day he came! But he was able to fix the low pressure in the sink by replacing the faucet. All other plumbing companies we had out said our only option was to replace the old galvanized pipes! I truly appreciate that Konner took the time to look at the issue, listen to us and come up with a solution that worked and not just say the most expensive option of replacing all the pipes! Highly recommend using Harts!"

"Austin and Corbin were our installers and they did a fantastic job! They quickly got the old shower out and had the new one installed and the bathroom cleaned up in less than 7 hrs. We LOVE our new shower and we wouldn’t hesitate to do it again!"

"Garret was referred to me by my brother in law who is a plumber. Garret worked on. Two of my rentals. Repairing a leak and replacing a kitchen faucet at one house and and at the second he replaced a hot water tank. The hot water tank had been leaking for awhile and Garret recommended that the floor be replaced(it was pressed partial board that had been softened by the leaking tank). He brought everything “up to code” so I know going forward that this. Project is completed. The work was done quickly and I paid a fair price for the work. I will be calling Garret in the near future to replace a few more Hot water tanks BEFORE. They damage the floor!"

"Working with DaBella has been a great experience. It was easy from the measuring of the bathroom, to the picking of the fixtures. Even the financing was a pleasure. Our salesman, Carson, was a great guy - he was friendly and easy to talk with. It was like visiting with an old friend!"

Plumbing FAQs, answered by experts

Yes, you can put a bathroom in a bump-out. Some homeowners build a bump-out to enhance their bathrooms with new sinks, vanities, tubs, showers, or linen closets. Depending on the layout of your bathroom and what you’re adding to it, you may need to install new plumbing or reroute your existing plumbing lines.

Flex is necessary for soldering copper pipe. This acidic paste attracts the solder, pulling it deeper into the joint so the solder fills all the gaps between the two metal fittings. While many solder products contain small amounts of flux, you need to apply the additional flux paste to ensure you achieve a water-tight fit between the two copper pipes.

Beyond keeping the entire plumbing system flowing, plumbing vents also help control gas and odors from entering the home. These vents also allow fresh air to enter your plumbing system, which helps improve water flow. A sure sign the plumbing vent is failing or needs repairs is if there’s a strong sewage scent coming from multiple points of the home.

No, a larger well pressure tank will not increase your home's water pressure by itself. Water pressure is determined by the pressure control switch on the well pump.

However, a larger tank does offer other benefits. It can store more water, which allows you to run water for longer periods before the pump needs to turn on. This reduces how often the pump cycles on and off, leading to less wear and tear on the pump and the entire well system. Consequently, a larger tank can help extend the life of your equipment and may prevent future pump issues that could affect water pressure.

If your goal is to increase water pressure, consider these alternatives:

  • Adjust the pressure settings on your tank to a higher PSI (pounds per square inch).

  • Replace your current pump with a model that has a higher flow rate, measured in gallons per minute (GPM).

  • Have a professional install a water pressure booster pump in your plumbing system.

  • If you experience pressure fluctuations, consider upgrading to a constant pressure system.

If your pipes are suddenly making loud noises, it could be due to any of the aforementioned issues. A water hammer is a common cause of this problem. Other potential causes include water pressure issues, loose pipes, air bubbles, and worn-out fixtures. Mineral buildup in the pipes can also cause loud noises.
