Not Enough Heat
When your water heater used to be totally capable of filling up the upstairs bathtub and washing the dishes and now it isn’t able to do that, it’s a sign of a developing issue. It might be as simple as going down and turning up the hot water temperature on the heater, but it may also be a capacity issue. This can be caused by a variety of things. For example, if you recently invest in a new washer and dryer, it might higher hot water demands that your previous one and you may need to get a bigger water tank if you want to use all of these amenities at the same time. Otherwise, it might just be a sign of the water heater getting older. It’s worth giving it a look if the problem persists after you’ve turned the water heater temperature up and you’ve seen no changes in the problem.
If you’re turning the hot water heater on and getting nothing, it’s likely a larger issue. If the water heater is gas-powered, it’s very likely that the pilot light has blown out in this scenario. This issue can be caused by a variety of things but it’s usually a bad pilot control valve or a bad thermocouple mechanism.
If your water heater is electric, the cause is likely a bad heating element. Sometimes, these mechanisms only need to be replaced, other times, the entire water heater will need to be replaced due to some issue with getting the part replaced or something similar. The replacement is a relatively easy repair if you’re well-versed in plumbing and how to repair water heaters, but we’d advise that you don’t attempt to do it on your own as a water heater is still a dangerous appliance since it deals with potentially high temperatures and could expose you to those.
