Answers to Your Frequently Asked Questions
We understand homeowners have a lot of questions when it comes to water heater repair. We encourage those questions and have answered some of the most common ones below.
By far the most common gas valve issues we see happen to water heaters purchased at big box home improvement stores. The issue is that plumbers cannot get those gas control valves because they are not sold, stocked, or carried by any plumbing supply house. They can only be mailed under warranty or purchased outside of warranty through the manufacturer’s distributor. In these cases, you can normally expect about a 3-day turnaround time.
It should be noted that Earl’s Plumbing will NOT perform work on or repair any water heater that is 12 years old or older. We do not want to take your money for what will likely be a short-lived or temporary solution. We do not do Band-Aid repairs!
What that means for the Frisco, McKinney, and Plano area is that if you have a PRV (Pressure Reducing Valve) installed then you are required by code to have an expansion tank installed.
Expansion tanks are required for traditional tank-type water heaters only. They are NOT required for tankless water heaters unless specified by the manufacturer.
How do you know if you have a PRV? Unless you have had water pressure issues or you’ve had one replaced, then you probably don’t know. But a good rule of thumb is if your home was built after 1999, it’s possible you have a PRV. If you live in Frisco, McKinney, Little Elm, or Prosper then you must have a PRV by city code. Less than 30% of homes in Plano have them, and less than 10% of homes in Allen.
Here are the most important things that you MUST know about expansion tanks:
- It is a steel tank with water inside. Eventual failure is inevitable. Be proactive.
- They will NOT last as long as the water heater, and they must be changed periodically. We recommend every 3 years, but 5 years at a maximum.
- Property damage by leaking expansion tanks is probably more common than a leaking water heater. The amount of damage depends on the seriousness of the leak (drip, spray, or full rupture).
- They must be installed horizontally, and when NOT installed properly, they will fail at a higher or more frequent rate. Improper installation can reduce hot water flow rates.
Once again, we recommend that you be proactive in replacing your tank water heaters and your expansion tank should this apply to you.
When adding or replacing a recirculation pump, special consideration must be given to the size of the home. Houses over 5000 sqft. will likely need a slightly larger and stronger pump than the standard. Homes over 5500 sqft. will definitely need a larger pump and homes over 7000 sqft. have an even larger pump. Ultimately, a properly sized pump will prolong the life of the system and the water lines while working more effectively and efficiently.
