"I had another company design my septic system replacement, but Paul re-designed it to avoid having to remove a 50+ ft tall tree and added a drainage system for the water from the gutters. The old no-longer-up-to-code 2-cesspool septic system was replaced by a drainfield and Ecoflow septic tank. The work was done on the days I was told workers would be here (unlike the company that drew up the first set of specs), and Paul and Jon were always friendly and great to work with."

"Done Wrong Plumbing - Buyer beware. I had them do work at my 85 year old mother's house. Always ask them for a detailed estimate in advance with hourly rate, time estimate and cost for parts when applicable. They repaired a leak under the master stall shower and when completed the floor of the shower now flexes and makes loud noise both in the shower and throughout the first floor of the house. This was not happening prior to their work. When I addressed the issue they sent out a rude tech who said if it is not leaking then it is not their problem. They charged $892 to put a fernco rubber boot on and cut a hole in the drywall to access. Invoice stated $128 to cut the drywall and not replace and $764 for plumbing. I asked for hourly rate and they refused to provide. Believe me you will "breath much easier" by choosing an ethical and better qualified plumber. You have been warned."

About Us- OUR MISSION At Mattioni Plumbing, Heating & Cooling, our mission is to groom the next generation of technicians by honoring our values of 5-Star customer service and operational excellence. OUR STORY For over seventy years, Mattioni Plumbing, Heating & Cooling, Inc.'s dedicated employees have proudly served the Chester County, Pennsylvania area with their knowledgeable, courteous, and professional service. A.F. Mattioni & Sons Plumbing & Heating was founded on the Mattioni family farm along the (back then) very rural Route 113 outside of Downingtown, PA in 1948. The original barn which housed the company still stands! However, a newer, larger building on the family's property is the current home for the third generation of Mattioni’s to run the service-oriented business, but their commitment to quality has not changed. OUR PROMISE Our promise to you is to continue to grow and modernize so that we can provide you with the best products and services. We will continue to stick to our roots of caring deeply for both our customers and our employees. We promise to live this every day and to continue this legacy.

"Overestimated the time to complete an 9 hr job by scheduling a 16 hr window (2 guys x 8 hrs) and charged for 16 hrs regardless. I'd imagine they did the same for the materials, 60 feet of duct needed but they quoted 200. Got the job done, but probably twice the price of what it should have been."

Septic Tanks questions, answered by experts

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.

A septic tank riser features a base ring that you need to install flush to the opening of the septic tank. After thoroughly cleaning the opening of the tank, fit the base ring over the opening and use a butyl sealant rope to create an airtight seal with the tank’s rim. Cut the riser rings to the appropriate height and stack them on the base ring. Then, install the riser lid. This task might be taken on by an experienced DIYer, but you should always call a septic tank professional if you are unsure of your skills.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Consider site conditions, soil type, required capacity, and system designs compatible with environmental protection regulations.
