Few things are more frustrating than a nice, hot shower turning cold. If your hot water runs out during showers, laundry, or dishes, your water heater may have an underlying problem.
Most causes, including sediment buildup and failing components, can be fixed. Identifying the likely issue helps you choose the right solution.
When you suddenly don’t have enough hot water to get through your daily routine, it’s time to take a close look. Several common issues can shorten your hot water supply, each requiring specific assistance from a professional plumber.
Over time, minerals like calcium and magnesium in the water supply settle at the bottom of the water heater tank. This layer of sediment displaces water, reducing the tank’s capacity. It also forms an insulating barrier between the heating mechanism and the water, forcing the unit to work harder and less efficiently.
A telltale sign of sediment buildup is a popping or rumbling sound coming from your water heater. To repair this, a professional performs a tank flush, an essential part of routine water heater maintenance. We use specialized equipment to safely drain the unit and clear out the hardened mineral deposits, restoring its efficiency and water capacity.
If your family has grown or you’ve installed new appliances, your demand for hot water may have outgrown your water heater’s capacity. Every tank-style water heater has a First Hour Rating (FHR) indicating how much hot water it can produce in an hour. If your demand exceeds this rating, you’ll run out quickly.
In this case, our technicians would evaluate your family’s peak hot water needs. The solution might be a new, larger tank model. Alternatively, many Ann Arbor families choose to upgrade to a tankless water heater, which heats water on demand and provides a virtually endless supply.
An electric water heater typically has two heating elements, one at the top and one at the bottom. If one fails, especially the lower one, the unit loses half its heating power. It might heat a small amount of water near the top of the tank but won’t keep up with ongoing demand, causing your hot water supply to run out quickly.
A professional plumber can safely diagnose this issue. We use a multimeter to test the electrical resistance of each element. If an element is burnt out, we can shut off the power to the unit, drain it, and install a replacement.
The dip tube directs cold incoming water to the bottom of the tank to be heated. If the dip tube cracks or breaks off, cold water gets dumped in at the top, where it immediately mixes with the hot water ready for use. This results in lukewarm water at the tap and a rapidly diminishing supply of truly hot water.
This can be a tricky problem to diagnose without experience, but it’s a straightforward fix for an Ann Arbor plumber. We can disconnect the cold-water inlet pipe to inspect and replace the faulty dip tube, restoring the proper flow of water inside your tank.
While some issues might seem minor, most water heater repairs involve working with electricity, gas lines, and scalding water, making professional service essential for safety and effectiveness.
