"Very responsive to recommendation, suggestions and phone calls. Was very helpful in advising the best way to do the project. Anthony was also very helpful to us in picking up the supplies and suggesting places where to buy specific materials. He was knowledgeable and supervised his crew appropriately. Most importantly is that Anthony stands behind his words and corrects any problems that arise without hesitation. He has a good work ethics and goes out of his way to make your experience favorable. Besides getting the bathroom done he also did some structural work for us including reframing slanted bedroom flooring, then laying new sub flooring and after that new engineered wood floors. He installed all new doors and moldings. Work did take longer then expected but it was partially our fault because we were slow at picking and ordering the supplies. i would use him for other projects without reservations."

"se  Rob is a dream come true. As a single woman running my own home and being very particular.....it is extremely important to be able to discuss the job, hear all the details, and employ someone who is honest, honorable, well qualified, neat, and highly informed. I first hired Rob for the drain problem. He accomplished that efficiently and neatly at a reasonable price. We discussed options for a back up for the sump pump. Having a finished basement, I am always concerned about water. I have never lost electricity during a rain storm....but the possibility always takes up space in my brain. I have a portable generator....but I have to be home to start it. Today Rob arrived on time and installed the back up for me. It took the whole morning as he predicted. He explained how it all worked and it is a beautiful thing. I so appreciate knowledgable and personable service. I highly recommend Easy Flow Drain and Mechanical LLC for any plumbing needs. Oh....one more thing...he noticed a leak in my fairly new furnace exhaust piping. He pointed it out and gave me several possible reasons for the leak so I could intelligently discuss it with the company that installed the new energy efficient furnace. What else could you want from a plumber? I was extremely satisfied and impressed with his service. I'm also grateful for Angie's List!!!!

"Costanzo electric was terrific! The estimate for the service was very reasonable considering the area and given by August the owner. He was able to come within a week and three men did the work. The men were clean and efficient and removed one fan and installed two new fans perfectly aligned. They cleaned up any mess and reviewed with me what they did and asked if I was happy. Great to find a reputable contractor and someone I can rely on going forward"

"In each and every instance, the plumbing technicians that have done the work have always been very professional in their approach. Meeting them at the door and the technician is putting on booties so as not to scratch or damage the floors, was the first sign that the company cared about its customers. After an assessment of the work requested was completed and a price was determined, the work proceeded. It was also just the beginning as in each and every case the technician demonstrated expert technical skill, in a deliberate and cautious manner. Drop cloths were placed down; tools and equipment were carefully located so they would be accessible yet out of harm’s way. The work was completed with great attention to detail. I especially noticed this when the double vanity work was being done. The technician, Mike, noticed immediately that both waste lines were, somehow back pitched. He advised me and agreed to go deeper into the project to correct the issue. Once completed, measuring for the new cabinets was critical for where the waste lines and supply lines had to go through the cabinets. He measured and re-measured to make sure they were correct and they absolutely were. The cabinets fit perfectly! The professionalism continued when it came time for the toilet installation. A new flange had to be installed because the old one was rusted out. Not problem. Then he got out the plaster and buckets to install the toilet. I asked why the plaster and he stated that it was company policy to mount the toilet in plaster to avoid any floor water from getting to the flange and to also stabilize the toilet. This was way and above what I expected. When he finished, the toilet was perfectly installed and with the plaster around the base, it looked nicely finished and was steady as a rock. The clean up for all the jobs was excellent. As you can infer from this review, I would highly recommend O’Brien Plumbing and Heating to anyone. The price is fair and competitive with other full service companies and knowing and seeing how professional and caring the technicians are, is a direct reflection on the owner and how he runs his company. I would never hesitate to hire them again and again."

Install Boiler questions, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
