"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!"

"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!"

"The sales experience was easy and pleasant. We're happy with the shower but I would have liked guidance about where to place the components. When everything was torn out we didn't know where to estimate where things should go, and we were off in our guesses. The shower heads weren't the same quality as what we had before."

"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

Like many other repair projects, the cost to fix a behind-the-wall shower leak depends on several factors. The cost of your repair may depend on the type of leak (from a clog or burst pipe), type of piping, and location of the leak. The extent of the issue and how difficult it is to access the pipes can greatly impact and increase your price. On average, you can expect to pay around $150 to $600 to repair a leaking shower.

The average cost to replace a toilet fill valve is around $100, and prices range from $50 up to $150, depending on your location, the experience of the plumber, and how accessible your toilet is. In most cases, a professional plumber can replace your fill valve in under an hour, although it might take longer if they also need to fix or replace other components at the same time.

In the best-case scenario, the pipe size is written on the side of the pipe. You’ll often find this with different types of plastic piping like PVC, PEX, or CPVC. For other types of pipes, you’ll have to measure. You can measure the outside circumference with a soft tape measure, then divide your measurement by pi. From there, you’ll have to use a conversion chart to get the nominal pipe size (the size you’d buy in the store).

Toilets typically connect to your main vent stack, a vertical pipe that runs through all finished levels of your home and exits through the roof. It’s located behind the walls, but if you have an unfinished basement or a utility closet, you may find a portion of it running the vertical length of the space. Some basement toilets use an air admittance valve instead, which is a small vent located in the wall directly behind the toilet that extends upward a few feet from the drain.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.
