Water Heater Replacement

When selecting the capacity of a replacement water heater for your home, it should be based on the number of people living in your home, and the peak demand that would be placed on the unit based on normal routines within your home. The water heater would need to supply adequate hot water at those peak times of the day. Also keep in mind the number of plumbing fixtures that require hot water in your home. Oversized bathtubs and hot tubs will require additional hot water, and this should always be factored in when making your selection.

Hot water heaters have a “first hour rating”. The FHR will indicate the water heaters ability to heat water back up as it is being used. This is helpful in determining the size needed as it relates to your peak demand usage.

Water Heater Installation

We routinely perform water heater repairs and replacements. We are stocked and able to take care of all your water heater replacement needs, including water pressure reducing valves, vacuum relief valves, gas sediment traps, expansion tanks, water shut-off valves, flood-stops, and any other plumbing item related to the safe installation of your water heater.

Our basic installation is defined as the installation of a new water heater in the place of an old one. The unit must be accessible for the plumber to uninstall and reinstall a new one.

Basic Installation of a water heater includes:

Water Heaters
  • Shutting-off your water, gas, or electric and draining your old water heater.
  • Removing the old unit and putting the new water heater in its place.
  • Connecting the new water heater to the existing code approved utilities.
  • Gas water heaters will be hooked up to the existing flue and gas line.
  • Electric water heaters are reconnected to the existing electric.
  • Water pressure and thermal expansion will be checked.
  • We will haul away the old water heater and any trash associated with the install.

There is a 1 year labor warranty on all water heater installations.
***Additional charges may apply if your current install is not up to current City or UPC requirements. We will do our very best to quote these additional charges over the phone, as we prequalify your installation. If you can email or text pictures of your current installation we can almost always quote a firm price.

Water Heater Warranty

Common storage tank-style water heater manufacturer warranties cover the tanks for 3, 6, 9, or 12 years. The Labor portion of the warranty covers the first year only. When considering your options, in regards to the tank warranty, the longer the tank warranty the better. If you know you are going to reside in your current home for many years to come, it would be money well spent on going with the longer warranty. Warranties are also transferrable if you plan on selling the home in the near future. In some cases, the water heater with the longer warranty is simply not possible due to the increased size of the unit, and your option would be limited to a lesser warranty. This can all be determined in advance with some simple measurements of the existing unit you have in place.

Expansion Tanks & Pressure Reducing Valves

When installing your new water heater, our plumber will check your current water pressure going into the home. Water pressure should not exceed 80 psi (pounds per square inch), this is according to 2009 Universal Plumbing Code. If the pressure exceeds the 80 psi, it has the ability to cause premature wear and tear on all plumbing fixtures throughout your home, and in many cases voids the manufacturer’s warranty on appliances. Pressure reducing valves and expansion tanks play an important role in regulating water pressure.

In addition to checking water pressure, our plumber will also determine if a thermal expansion tank is required. When water is heated it expands. Water is not compressible and the added volume created by this expansion must go someplace. When water is not flowing in the system, pressure reducing valves, backflow preventers, and other one-way valves are creating a closed system. This closed system eliminates a path for the expanded water to flow back into. This in turn creates pressure in the system.

Water Heaters

Thermal expansion of water in a closed plumbing system can create a number of unnecessary and potentially dangerous problems. These include the build-up of unusually high pressure in a system, pressure surges and the continuous dripping of a temperature and pressure (T&P) relief valve. Dripping faucets and leaking toilet tank ball cock fill valves can also indicate thermal expansion.

Thermal expansion can also create more serious problems if not addressed. When extreme pressures are built up in a water heater, internal parts may fail such as the internal flues, fittings or possibly water connections. If a flue way collapses it can lead to the potential release of carbon monoxide into the home. Thermal expansion can also lead to a ruptured or distorted hot water heating tank and this may void the manufacturer’s warranty.

There are plenty of repairs that are a waste of money if done right before a sale. On the other hand, some repairs have a high ROI (return on investment) because they can increase the desirability of your home and are often inexpensive.

But, the following things should be repaired before you finally sell your house:

  • Minor kitchen repairs, such as painting new countertops, and installing new fixtures
  • Small bathroom repairs, which include replacing missing tiles, cleaning up or replacing grout, and adding a new coat of paint, might be necessary.
  • Cleaning up the exterior & adding accents, like basic landscaping, that increase curb appeal.
  • Improved lighting to make the home a more inviting and spacious feeling.
  • Painting the rooms that need it.
  • Refinishing hardwood floors.
  • Make sure everything works, like doorknobs and locks.
  • Pre-sale inspections—to give you time to fix what the inspector finds.

After a $9000 quote from another company, I called Lone Star. I was set up with 18 months at 0 interest and the total was $2800. I got a water softener and water filtration. The prices are clearly listed on their website. The installers are friendly and knowledgeable. I highly recommend!

Garrett was honest, fast and friendly. We had a water softener throwing up an error. He gave us the choices of what could be done or getting a new one. We went with the new option and there was zero pressure.
