"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

You’ll need two sizes of pipe to plumb a bathroom. You’ll use a 1/2-inch pressure pipe for your supply lines that run from the fixture to the larger 3/4-inch supply lines that run through the house. For drain lines, you’ll need a 3-inch PVC pipe for your toilet, a 2-inch PVC pipe for stand-alone showers, and a 1 1/2-inch pipe for a shower/tub combo and the bathroom sink. Each fixture’s drain will run to the 3-inch main drain that runs through the house.

Having the right size pipe ensures proper drainage and helps protect against clogs and other plumbing problems. A pipe that's too small will take longer to drain, which can result in backups. And solids can build up in pipes that are too large. Choosing a pipe with the appropriate volume also means it will be able to handle water pressure, which is the force behind the water.

Adding plumbing to a detached garage or shed can increase the value of your house, especially if the garage is properly insulated, conditioned, and finished so that it can serve as additional living space—as a rental property, for guests, or as an in-law suite. However, it’s unlikely that the cost to add plumbing to a detached garage will increase the property value enough to recoup your investment (and don’t forget: you’ll likely see increased property taxes after the renovation).

No, shower valves and cartridges are not universal. They must match and typically come from the same manufacturer. Mixing and matching different brands is unlikely to work and can cause issues like leaks or malfunctioning faucets. To find the correct replacement, check the old valve or cartridge for a brand name, model number, or serial number. If you cannot find this information, contact the manufacturer or check their website to determine which parts are compatible.

Yes, ammonia does damage pipes if used or disposed of improperly. Although ammonia-based cleaners are commonly used to unclog drain pipes, they either come already diluted or instruct the user to dilute them before use. Otherwise, undiluted ammonia is too caustic and could corrode certain plumbing types, such as PVC.
