Genie Bath Systems provides homeowners with custom bath remodeling solutions, to include a full-line accessibility needs. All of our products are custom made in the USA. Factory Certified Installation.Lifetime Warranty.100% Financing . PLEASE NOTE: WE DON"T PERFORM KITCHEN REMODELS

"Last October, my sister, an elderly veteran living alone, contracted Genie Bath Systems to remodel her master and guest baths. She was diagnosed cancer and passed before the remodel was complete. Which, to be fair as we were not able to work with Genie while attending to my sister. The contract was expensive. Very expensive. The cost of the remodel is close to 1/4th the value of her home. I noticed there were issues with the remodel that showed a surprising lack of attention to detail. Genie sent people to address the issues twice. Yet issues remain. My calls to my contact at Genie are now being ignored. Also, the only document I have for the remodel is the contract my sister signed. It is not detailed. I have and continue to ask for a breakdown of the cost. An estimate or work order. This request is also being ignored. I am disappointed and have to wonder why Genie will not provide this information. I have several other questions for Genie that I will not go into here. But based on my experience, I cannot recommend Genie. In fact I would warn anyone considering Genie to be very careful about the cost of the contract."

"Expo Home did a fantastic job from beginning to end. Maurice our sales representative came to our home and very thoughtfully walked us through everything. He helped us to make a difficult and expensive purchase decision. The contract was signed Friday evening and the work was completed by Thursday afternoon. The installers Ricardo and Omar arrived promptly on install day morning at 8am and worked quickly to do all the work by 4pm. They respected our home and kept work areas clean with tarps. Omar especially kept me informed of the progress of the project throughout the day. Ricardo as the lead installer was very skilled in performing the work and knowledgeable about all the details of the project. I would highly recommend Expo Home for your next tub to walk in shower conversion. Thanks to everyone at Expo Home team and satisfied to be member of their family."

"We had SMELSCER PLUMBING install two 50 gallon water heaters in 2018, one upstairs & one downstairs @ $750 each, with a 6 YEAR WARRANTY. Within 1 YEAR the water coming from the upstairs one smelled awful - like rotten eggs. They drained it and charged us another $200. NOW the UPSTAIRS water heater HAD COST US $950. Within 3 YEARS (of a 6 YEAR WARRANTY), the upstairs water heater QUIT WORKING. They said it had to be REPLACED (UNDER WARRANTY) & said the LABOR TO INSTALL IT would be $600, meaning the upstairs water heater NOW COST $1550. Also, even though they were installing a NEW WATER HEATER, they would only honor the 3 YEAR WARRANTY left on the FAULTY WATER HEATER. WHAT SHOULD THEY HAVE DONE? They should have gone back to the company and NEGOCIATED (on behalf of their client - US) a NEW WATER HEATER with a 6 YEAR WARRANTY, and NEGOCIATED with the company to PAY THE $600 INSTALLATION FEE. They DO NOT BACK UP THEIR CLIENTS!!! AVOID THIS COMPANY!!!"

FAQs for water heater installation and replacement projects in Waco, TX

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.

For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.

Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.

Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.

A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
