You may not think much of it, but warm water from your showerhead can be perfect for cold mornings and evenings. However, the lack of warm water when you most need it can be highly unpleasant and inconvenient. Such an occurrence could also mean an underlying issue with your plumbing. Thankfully, you can hire an expert to fix this plumbing problem and restore warm water in no time. Here are possible reasons why your shower doesn't have hot water.

Valve Problems

The shower regulator combines hot and cold water to ensure the right water temperature. However, the valve will fail to work as required when the washer and O-ring deteriorate. In this case, you will have cold water from your showerhead due to malfunction.

When you encounter this issue, contact a plumber immediately for assistance. This professional will check the valve and replace the damaged components. That way, your shower valve will mix water effectively for a warm shower.

Tank Seepage

On other occasions, your tank might be the reason your shower has no hot water. Typically, leaks within the tank can cause a decline in water pressure. In other cases, your tank could deplete water due to extensive seepage. Also, the problem can worsen if you're running other appliances and taking a shower at the same time. If this is the case, you may need to repair or replace your tank to restore a warm water supply. 

Defective Heating Elements

An electric water heater comes with heating elements to ensure proper function. For example, a thermostat will set the right temperatures and ensure a consistent warm water supply. However, your tank will not receive the signal to heat and discharge warm water if this device has issues. In other cases, the wrong settings can make your shower water cold. That said, adjusting the temperature setting can restore a warm water supply. If this doesn't do the trick, you may need to replace your broken thermostat.

Small Pipes

Your piping system could be another cause of cold shower water in your household. In this case, the water supply to your shower can decrease when you flush the toilet. When that happens, your shower valve might not have adequate water to mix. Consequently, your shower will discharge cold water until the toilet tank fills up. If this is the case, you will need a plumber to replace your small pipes with larger ones. That way, the water supply to all your plumbing fixtures will be even.

The above are potential reasons why your showerhead is releasing cold water. That said, no matter how small the issue may appear, you must get professional help. A plumbing contractor — such as Bud's Plumbing, Heating, Air Conditioning & Electric — can inspect your shower and other fixtures to decide if they need repairs or replacement.
