No Hot Water? Here’s What to Do


You hop in the shower ready to lather up and start your day, but instead of being showered in hot, soothing water, the shower head you once considered a friend becomes an enemy when it starts dousing you with an ice-cold stream. What’s going on? Well, you’ve learned the hard way that your home has no hot water. It’s time for you to get down to business after a rude awakening like this. We can be the professionals to help you do it.

Unfortunately, your water heater is probably the culprit behind the lack of hot water. If you’re looking for a plumber in Cranberry Township, PA to set your home back on track, then it’s time to give our team a ring. All our technicians are skilled and can help you get the service you need.

A Few Troubleshooting Tips

There are a few things you should consider before you jump for your phone. We’ve made a quick checklist for you to reference:

Is the Thermostat Setting Correct?

Yup! You read that correctly: your heater and air conditioner aren’t the only devices in your house that run off of a thermostat. Your water heater has a thermostat too (a.k.a. an aquastat). The ideal temperature for a water heater is somewhere between 120° and 140°F. If you’ve noticed your aquastat setting has dipped below the 120 mark, then it’s a great idea to turn it up and getting your water flowing at the right temperature again.

Be cautious, however. If the aquastat is miscalibrated, you may turn it up too high and create a scalding hazard. Test the hot water first before jumping into a shower after raising the aquastat.

Is the Water Heater Properly Sized?

Is your water heater the right size for your home? Before you answer this with a knee-jerk “yes,” consider if your water heater’s needs have changed in the past few years. Maybe a smaller water heater was right when you first moved into your home, but now your family has grown, or you’ve added on to your home and the water heater is just not cutting it anymore. This is a sign you to upgrade your water heater ASAP.

Is the Pilot Light Still in Shape?

If you have a water heater that runs on natural gas, then its pilot light should always be burning bright blue. If the pilot light has turned off or if the color has turned red, yellow, or orange, schedule an appointment with our professionals to fix it. We’ll ensure you get the best functionality possible.
