"Patrick was able to correct all of my problems.  He was quick, provided excellent work, explained to me what he was doing and showed me what he discovered.  Once he found the fracture in the toilet, he was able to order and install the new toilet the next day.  He gave me a fair price on the toilet and labor and even replaced some of the connecting plumbing.  I am more than happy with his work and would recommend his service to anyone needing plumbing work.  He recommended eventually replacing my other two toilets and recommended which to replace first.  I appreciate his work, professionalism and efficiency.  I will definitely use him for the replacements and any other plumbing needs that I have.

"As a landlord I have had my fair share of plumbing issues.  I am particularly pleased with the service I receive from John owner of Knock You Plumb Out Plumbing.  John has replaced sewer lines for me along with other plumbing problems.  I have even referred John to friends, something I normally am hesitant to do because I don?t want to be involved if there are problems with the quality of the work.  But with Knock You Plumb Out Plumbing I am confident of quality work and service.  I highly recommend John.

"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."

Septic Tanks FAQs, answered by experts

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. 

We’ve explained how deep-rooted plants can damage a septic tank from the outside, but plenty of things can ruin it from the inside, too. For example, flushing bulky items (like paper towels, diapers, and wipes) can clog your septic tank. Cooking oil, grease, and household chemicals can also harm your system. And since a new septic system costs between $3,460 and $11,450, it’s worth following these guidelines.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.

Frozen well pipes make themselves known quickly, as your faucets slow down to a trickle or shut down completely. If you notice a serious reduction in flow in the winter from toilets, showers, kitchen faucets, and other plumbing fixtures, a frozen pipe or two is to blame. Another tell-tale sign is frost or ice on exposed pipes outside. 

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.
