It can be frustrating to not have hot water in your bathtub, especially if the other plumbing is working perfectly. There are many reasons why a bathtub may not have hot water, even though the nearby sink has hot water. While some of these problems may require professional repair, others can be fixed by you. Investigate the potential problems that could be causing your tub’s cold water to stop flowing before calling a plumber.

A Defective Faucet

Problems with bathtub faucets could be caused by a defective faucet. This is especially true if the faucet handle does not open and water doesn’t come out. This is a sign that the water flow valve has failed. It’s a hassle, but it’s a good sign because a faucet that is broken is cheaper and more simple than other options.

You can repair a tub faucet by yourself if you are willing. Turn off the water supply to the faucet and then remove it with a suitable-sized wrench. Measure the hole in which the faucet was installed. Then, purchase a faucet that matches this measurement. Follow the instructions to replace it.

Water Heater Malfunction

Hot water is essential for bathtubs. A malfunctioning water heater could be the reason you are no hot water in nz. An electric water heater may have one or more heating elements that are not working correctly. This could cause water to flow cool, or even lukewarm. You may need to replace the heater’s thermostat. You may only need to adjust the thermostat, like relighting a pilot light on a gas heater, or restarting an electric heater.

The dip tube can also break off in gas and electric water heaters. This allows hot and cold water to mix. A problem with the shower mixing valve or tub could also prevent hot water from mixing with cold. If you suspect the heater is the problem, hire a professional to inspect it.

Clogged Pipe

A clogged drain could also be a reason your tub doesn’t get enough hot water. This is more likely in older homes with pipes that have been around for many decades. Sometimes, old pipes can become clogged by mineral deposits from chemical imbalances in the water. Even though the hot water faucet at the sink is functioning fine, this can prevent hot water from reaching your bathtub faucet.

If you have hot water but not hot after replacing the faucet, it could be a clogged pipe. Get a plumber to flush out the pipes and restore them to normal functionality.

A Hidden Leak

Hot water can flow badly or not at all if there is a leak in the hot water pipe. A leak is almost certain if you see water damage or stains in the ceiling or crawl space beneath the tub. It is easier to spot a leak if the tub is located on the first floor or apartment of a slab-foundation house or apartment. If you suspect that this is the source of the problem, a plumber should inspect the system.
