"As soon as I went on Angieâ s list they contacted me. He asked for pictures of our hot water heater and all the documentation on it. By the end of the day he sent me a quote for two different models. The night before he came to install the new heater he asked to see it to be sure he would have everything he needed. Mr. Rizzo is an excellent plumber and a pleasure to work with. He covered all the floors I would definitely recommend him. He was a rare find!"

"Excellent Plumbing was fantastic - he installed a new faucet, vanity, and water filter for me. Super punctual, really professional, very communicative, and paid close attention to detail. Everything's working great. What really stood out was Joe's dedication. He came back to check on the work and found an unrelated issue with my kitchen sink (which was already there). He gave me some great tips on how to fix it. I highly recommend Joe and Excellent Plumbing & Heating for any plumbing work. He's super skilled and has awesome customer service."

"Just Rite Heating & Cooling installed our central air conditioner today. The team of five were on time, courteous, friendly and hard workers. They laid down runners to keep the interior of my house clean. The boss, Eric, explained how each part of the system components worked. Together we worked out the placement of the ceiling registers in each room. After the system was completely installed I was instructed on the how the new thermostat controlled both the old heating system and the new air conditioning system. Best of all the installation was completed in one day!"

Water Heaters questions, answered by experts

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.
