Frequently Asked Questions

Have a question about your plumbing issues? Here are some common plumbing questions and answers.

There are a few things to keep in mind when it comes to hot water system repairs. First, consider the age of your system. If your system is relatively new, it may simply be a matter of replacing a faulty part. However, if your system is older, it may be more cost-effective to replace the entire unit. Second, think about the warranty on your system. Many manufacturers offer extended warranties on their products, so it's worth checking to see if your system is covered. On Call Plumbing are the experts and offer monthly discounts! So if you're in need of hot water system repairs, On Call Plumbing is here to help. Give us a call today!

A Hot Water System Repair is not a job for most homeowners. It requires someone with the know-how and the right tools to get the job done right. That's why it's always best to hire a professional to repair your hot water heater. A professional will have the experience and the expertise to replace your heater quickly and efficiently. They will also be able to troubleshoot any problems that may arise during the process. In addition, a professional will be able to repair your hot water heater in compliance with all local building codes. So if you need to repair a  hot water heater, be sure to give On Call Plumbing a call!

Here are some ways that you can prolong the life of your Hot Water System and save yourself in the long run.

  1. Regular maintenance - check your heater regularly
  2. Switch off when not using for extended periods - if you are away on holidays be sure to turn it off.
  3. Have a Plumber complete an assessment and service at least once annually.
  4. When installing, put in a low traffic location as it will not be bumped or tampered with.

When it comes to hot water heaters, there are several types to choose from. The most common types are gas, electric, and solar. Each type has its own advantages and disadvantages. Gas hot water heaters are the most popular type because they are relatively inexpensive to operate. Electric hot water heaters are more expensive to operate, but they are more efficient and easier to maintain. Solar hot water heaters are the most expensive to install, but they are the most eco-friendly option. When choosing a hot water heater, it is important to consider your needs and budget. On Call Plumbing can help you select the best option for your home.
