At Water Heaters Only Inc, we’ve had the opportunity to deal with almost every water heater problem over the last 54 years in business. We receive many calls for problems with water heater, but there are 3 problems our customers ask about most frequently. The top three issues are our customers ask about most often are: I have no hot water, my water heater is leaking and why does my water heater make that awful sound, it that dangerous? These three issues happen for different reasons. We will explain below in detail about each issue.

No Hot Water

When you have no hot water it is usually a sign that the water heater pilot light has gone out. The first thing to do is to try and relight the pilot. If your pilot relights, check it again in about 30 mins. If it is still lit than the issue my be solved. If the pilot light has gone out again, it means that a part has started to fail and may require replacement. If the pilot does not light at all or goes right out after you try to light it, you may have a part that has failed and the tank will require service. This is a good time to call and speak with one of our water heater experts to start a conversation about the problem and find a solution or schedule service. Our water heater experts answer the phone 24/7/365 and are happy to help with a little troubleshooting over the phone.

Water Heater Leaking

A leaking water heater is a clear sign of a problem. We always recommend that you look around the water heater and make sure the leak is not coming from a washing machine or air conditioning unit. Once you have ruled out other possible causes for a leak and you are sure it is the water heater leaking, it’s time to find out why the water heater is leaking. If you notice a leak at the top of the tank coming from a pipe or a plumbing fitting, you may be in luck and only need to have a minor plumbing repair. Something as simple as replacing the pipe or the plumbing fitting may fix the problem. On the other hand if the water heater looks like it is leaking from the bottom or you just see water pooling around the bottom of the tank, then it is most likely time to replace the water heater. This is often a sign that the internal tank has cracked and water is flowing out from inside the water heater.

Noisy Or Loud Water Heaters

When your water heater starts “banging” or “rumbling” or making other load unusual noises it most often is caused by sediment build up inside the tank. When the water heater turns on the heat itself and there is a layer of hardened sediment at the bottom the water heater will often make a loud noise. This is the tank expanding as it heats and the sediment heating up will cause the water heater to emit strange sounds. This is not typically a dangerous issue, although it can be bothersome. This is often a precursor to water heater failure. It also means the water heater is working much harder than it should to heat the water and is wasting energy.

Other Water Heater Issues

Sometimes a problematic water heater is not a problem with the water heater at all, but the conditions around it that are causing the issues. Today’s water heaters are very sensitive to their surroundings. Tanks need proper ventilation to breath so they do not overheat. Make sure there is clear space around your water heater and if your water heater is in a closet, make sure there are vents on the door to allow air to flow inside the closet. Water heaters also need to have adequate venting so they do not back draft, leaking carbon monoxide inside and causing problems to the baffle and parts. Make sure your draft hood is attached properly and that your vent runs at an uphill angle.
