We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

Water Heaters questions, answered by experts

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

Whether to repair or replace your water heater is determined by your water heater’s age and condition. If you have an older model reaching the end of its life expectancy or if your water heater has been having problems more frequently than usual, replacement might serve you better. If you’ve been thinking about upgrading to a tankless water heater, then you may not want to spend any further on repairing your old one, either.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

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.
