Usually, the two most important questions you want to be answered are… What’s wrong? …And… How much is it going to cost? At Luke's Plumbing, we don’t have a problem giving you a price over the phone. Many Houston homeowners who call us are frustrated because they have called other Houston plumbing service companies and have gotten a run-around when it came to getting a price. It is sad to admit that our industry is plagued with plumbers who intentionally will not give you a price or even a ballpark estimate over the phone because they want to get in your home where they can pressure you face to face into spending more than you should. One of the highest numbers of complaints to consumer protection agency is for home improvement and service companies.. Plumbing license: MPL 37466. A/C license: TACLB 53102E. Call us today for all your plumbing needs!

John Moore has been a family-owned and operated business since 1965. We understand the trust you place in our company when you invite us into your home. “Call John & Get Moore” is more than our company’s slogan; it’s our pledge to you. We’ll explain everything and provide upfront, honest pricing options, so you feel confident from start to finish. We only hire the very best craftsman and give them the very best training and resources. All of our work is backed by the integrity of the John Moore name.

"recently called John Moore Services for what should have been a simple plumbing issue — a clogged bathroom sink connected to my air conditioner drain line. I reached out after seeing their TV commercial promoting clogged sink service for “about $69.” What I quickly discovered is that this advertised rate applies to an extremely narrow and unadvertised category of sinks that almost no real-world situation meets. My straightforward, less-than-20-minute fix was quoted at over $600 to snake. This is an outrageous markup for such a basic job. As a former small business owner, I find these tactics troubling. This is a textbook example of bait-and-switch advertising — grabbing attention with a low price, then upselling with inflated charges once the customer is committed. Practices like this harm consumers and tarnish the reputation of the many honest, hardworking service providers in our community. Shame on you, John Moore Services. My strong recommendation: Do Not Use."

Water Heaters questions, answered by experts

The amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.
