Ennis Plumbing is open for your needs during the current health crisis.We wear masks and practice social distancing. ***Super Service Award Winner 2014-2020***Have a current masters and contracting license, also insured. Never a trip charge. Always available-nights and weekends. I will always give a honest and up front answer. Ennis Plumbing LLC is also a member of the BBB with A+ rating and is a accredited business

"On a Monday morning, we woke up to a flooded basement bathroom floor. We called a few highly recommended Angie's List contractors, and James and his son were able to squeeze us in on Tuesday morning between appointments. They called 30 minutes before they arrived to inform us they were on their way. Once they arrived, they worked diligently to identify where the leak originated. They carefully removed only one tile from our basement bathroom shower to repair a cracked pipe in the wall under our kitchen. Once repaired, it was determined there were two more cracked pipes in the wall. They spent the better part of an hour identifying the leaks and where in the wall the cracked pipes were located. Again, they carefully cut discreet holes in the wall to repair the pipes. They recommend we have our pipes snaked to clear out any blockage and referred us to gentleman that was able to come the same afternoon. The snake he brought was 25 feet, and we were now experiencing some slight leakage under the kitchen sink. James texted us that evening to see how it went. We told him, and he said he would stop by in the morning to check everything again. After several tests of the dishwasher, full sinks, etc., it was fixed. Whatever was caught in the pipe was gone. We decided to have our main line scoped just to be safe. James said we didn't need to and recommend we cancel our appointment, but referred us to a reputable company anyway. The scope was clear, but the gentleman recommended we have our clean out replaced. My husband decided to replace the cap instead and texted James to discuss his plan to do so. James and my husband have been texting for the past few days to ensure all is well with the pipes and the cap. James and his son are incredibly thorough and follow up on their work. I would highly recommend them to anyone looking to have pipe/plumbing repairs. Thanks!"

"Terrible experience. I had hired Mike multiple times previously and had great outcomes. Then, I wanted to replace plumbing in half of my home. He send his employee, who was a total nightmare! Screaming profanities in my home, never working, my husband ended up asking Shawn to leave. One of Bathrooms needed to be redone, because Shawn did all the work incorrectly. Mike had the nerve to tell me "he was losing money this job." Well, Mike never checked the other areas Shawn had finished. I had to redo my kitchen plumbing 5 years and ago.

Water Heaters questions, answered by experts

Tank-style hot water heaters need replacing about every six to 15 years, while a tankless model can last 20 years or more. Over time, water heaters fill up with sediment that can start causing issues. If your unit is ten years old, start thinking about a possible replacement. Flushing your tank-style water heater annually and having routine maintenance done can increase the life span of the unit.

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.
