"Very professional and courteous.  Cleaned up after their work.  It was the best experience I have ever had with a plumber.  They are locally owned and very responsive - unlike some of the very large companies.  The pricing was reasonable and they worked with me on the options of which replacement tank to use.

"**To everyone** This is the plumber you want to call !!! Typical FANTASTIC service call from "Knock You Plumb Out Plumbing". Our family was dead in the water, plumbing wise. We could not flush a toilet. Water was rising everywhere and all drains were gurgling. John Harris (owner), and a 2-man crew arrived 30 minutes after I sent a "Help!" E-mail to him. I could not believe he got to my home so quickly. John and his crew went to work diagnosing the problem. John started removing the plug on one end of my sewer system and found that my entire sewer system was under tremendous pressure due to all of the plunging I was doing. Before he started taking any more pipes apart in the basement, he asked if I had a septic system. I told him that I did and he said that my septic tank was probably full. John went out back, took the lid off of my septic system and found that the tank was almost completely full! Thanks to John, I then knew what the problem was and it was an easy fix. I had a septic cleaning company come out within a couple hours, and my house was back to normal. Thanks again John. This was the second time in 3 months he helped me out and I could not be happier. This guy is my only plumber?forever!

"Ray phoned me prior to arrival letting me know that he would be delayed for scheduled appointment which I really appreciated. He checked the sump pump and drainage system to determine if it was working properly. He determined that the line needed to be jetted and sump pump pit cleaned out due to the presence of debris in the pit. He returned and completed the cleaning of system and found a blockage in the basement stairwell drain. I am planning to have Bailey's Plumbing to remove the blockage and correct the problem. I thankful to have a plumber whom I feel I can trust. Ray kept me informed as he performed the jetting of the the French drains to see the debris and see the air rippling into the sump pump pit. He also showed and explained where the blockage was and how it affected the flow of water from my stairwell area. He gave the free estimates within a timely fashion and I felt he did not use any hard sell dialogue to influence my decision to hire him to complete the work.👍"

"They called me right away once I submitted the request through Home Advisor and arrived the next day. Work was done quickly. My questions were answered and they will remind me in three years to have my septic cleaned again. Can't ask for more than that! Not sure of the value for the money, did not price around."

"We needed our water heater replaced. It was somewhat complicated because we wanted to upgrade the tank in size, but we had limited room for it. There was some back and forth in finding the appropriate tank, but the salesperson and technicians were very pleasant to work with throughout the whole process. When the pipes were moved and the tank was installed, it was done efficiently and professionally. We are very happy with our experience and the final product."

It went very well. Jeffrey Morrissey (master plumber & gas fitter) was able to locate the leak point that cause water to seep down from the inside of the back basement wall to the outside in a vertical fashion. We discovered the leak on the outside wall after turning on the water hose for the first time in the Spring. We also got 5 min of help to check our sump pump too (nothing wrong there. Just got a quick lesson on how to check if it's still working even though we have not heard it run for years).

He ended up cutting out the copper portion where there was a hole & clamped the other part for the fix. So far so good - it's holding well. It was found that that area was in need of additional insulation. With the extreme temps this past year, the hose bib line ended up with a hole (we've lived in the home for almost 20 yrs & this is the 1st time we had trouble). He left the drywall opening for us to repair since we needed to add more insulation (used spray foam around the repair site). 

Jeffrey Morrissey was on time and the first to respond via Home Advisor search; was friendly/easy to work with, helpful, careful about our home. No complaints. I saw that he was not on Angie's List, so we're hoping our good service experience will add his company on this list. Good service!

Septic Tanks FAQs, answered by experts

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
