A leaking water heater can cause significant damage, but you can act quickly to minimize it. Here's what to do first: Shut Off the Water Supply: Find the water shut-off valve for your water heater. It'll be a handle near the top or bottom of the unit, usually a ball valve (lever handle), gate valve (round handle), or globe valve (similar to a gate valve but often with a slightly different body shape). Turn it clockwise until it's completely closed to stop water flow to the unit. Turn Off the Gas (if applicable): For gas water heaters, locate the yellow gas shut-off valve on the gas line leading to the unit. Turn the handle perpendicular to the pipe to shut off the gas. Drain the Tank: Connect a garden hose to the drain valve located near the bottom of the water heater. Run the other end of the hose to a nearby floor drain or outside to safely drain the water from the tank. Next, Call the Pros! Once you've stopped the leak and drained the tank, call Nxt Gen Plumbing, your Longmont water heater professionals, at 720-910-4195. We'll get you on our schedule right away. When we arrive, we'll thoroughly assess the situation and provide you with clear options to either repair or replace your water heater.

There's no single "better" option; it really depends on your home's needs, your preferences, and specific factors like your location. An expert plumber can help determine the best fit for you. https://www.youtube.com/watch?v=uh1wkHxDqmM

Location, especially elevation and incoming water temperature, significantly impacts tankless water heater sizing and performance. For example, in Colorado, at 5,280 feet above sea level, the thinner air means less oxygen for combustion.

BTU derating is the reduction of a natural gas appliance's effective heating capacity due to high altitude. In Colorado, for every 1,000 feet above 2,000 feet, you lose about 4% of accessible BTUs. This means a tankless unit rated for 11 GPM at sea level might only produce around 4.4 GPM in Colorado.

That depends on your household's hot water demand. While a single tankless unit might suffice for homes with up to three bathrooms, larger homes or those with higher demands may require two tankless units or a specialized system design to ensure adequate hot water supply.

Short answer: no. Electric tankless units are typically designed for point-of-use applications. In warmer, lower-elevation areas like Arizona, they might work for small homes. But in Colorado, the temperature rise required (Delta T) is about 80°F during winter, which is too much for these units to handle efficiently. They can be used for limited applications like a wet bar or a small commercial bathroom sink—but not for whole-home use in our climate. Here in Colorado, professional licensed plumbers usually install high-efficiency natural gas units, typically 199,999 BTU or at least 160,000 BTU for a small studio. If you're looking for reliable performance in Colorado, stick with a high-efficiency natural gas water heater.

Gas line sizing for a tankless water heater can be complex—there are multiple factors at play. In Colorado, a common standard we follow is to run a 1" natural gas line and reduce it to 3/4" within 5 feet of the unit. We typically use solid black iron piping due to its strength and reliability, plus it doesn't require grounding like corrugated CSST. But sizing isn’t just about pipe diameter—length, pressure, and total demand on the system all matter. A licensed master plumber in Longmont (or anywhere in Colorado) should always perform a “longest run” gas load calculation to determine how many BTUs your current setup can support. For example, a 1" gas line rated at 0.5 in. w.c. may handle around 257,000 BTUs at 60 feet—but once you factor in other appliances like your HVAC, fireplace, stove, or outdoor BBQ, your system may no longer meet the demand. That’s why a proper load calculation is critical. Any qualified plumber should give you a detailed gas load report to show how your system stacks up. If they skip this step and just estimate, you risk poor performance and inconsistent hot water—especially in colder months. Tankless water heaters are a proven, efficient solution—but only when installed correctly. That’s why working with a skilled, transparent plumber makes all the difference. At Nxt Gen Plumbing, we’re here to help you make smart, informed decisions for your home.
