"Mr. Rooter is an awesome company. This is the second time we hired them. We had a drain problem with the washing machine they came out with in one day and fixed it. It took them longer than expected because of the age of our house and the old pipes what are installed. They did not charge us extra for their time then the estimate he gave us after arrival. They left the house super clean and were very professional. Very rare to find a company like that."

"Alex and Donavan were very thorough. Discovered more than what we called them for. We originally wanted information on sealing cracks to eliminate cricket infestation coming through cracks in stem wall. We were not interested in repairing foundation rebar which is typical in slab homes in AZ. They were knowledgeable and honest in their evaluation of our home."

"I had an excellent experience with City Plumbing and Rooter AZ. What started as a mainline leak quickly turned into a full replacement after proper leak detection, and I’m honestly grateful I went with them. From the beginning, they were professional, transparent, and easy to communicate with. They took the time to explain everything clearly so I understood what was going on and what needed to be done. After getting quotes from multiple companies, their pricing was fair and straightforward—no surprises or pressure. Most importantly, they made me feel taken care of throughout the entire process. The work was done efficiently and with great attention to detail. If you’re looking for a trustworthy plumber who stands by their work and treats customers right, I highly recommend them."

"Recently had a concrete patio with a walkway and steps installed. The entire process was outstanding. From the initial consultation through project completion, Anchor was professional, responsive and easy to work with. The patio looks fantastic and has transformed the appearance and functionality of our outdoor space. If you’re looking for a reliable concrete contractor who takes pride in their work and delivers high quality results, I would definitely recommend the guys at Anchor."

"We are staying at an Air Bnb in Prescott. On Saturday the bathroom toilet became clogged and backed up into the shower in the guest bathroom. The owner contacted Ben Franklin Plumbing in Prescott. Andrew Korland plumber came at 8 pm after completing another job. He was professional, courteous and had great attention to detail. Once he assessed the problem , he contacted the owner before beginning the repair process. She approved the work.Andrew immediately began solving the problem running almost 80’ of coil to unclog the drain at the clean out site. We had a working toilet by 9pm. Andrew was calm and explained what he was doing before and during the process. He also provided his contact information afterward in case we had questions or concerns. We are impressed with Andrew’s response time and excellent work ethic."

Foundation Drain Installation questions, answered by experts

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.
