"This the second time I have called Mr. Rooter and once again I am delighted with their services. I requested that Clinton come and he repaired or replaced all of my outdoor hose bibs and refitted the drip system fittings. He made several trips to hardware stores for specific pipe fitting and was quick to resolve any issues I brought up concerning ease of use or accommodation to existing requirements. He also checked all the drains and poured in a drain cleaner treatment. We received a discount coupon after our first visit which was applied to the new total. I will always call Mr. Rooter for pluming issues and also ask them so send Clinton, and will highly recommend their service to others."

"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

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

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 move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.
