Why Is Your Tuscany Shower Faucet Not Hot Enough?

  • Problems With Shower Faucet Cartridge

Sometimes, a shower Cartridge is a primary culprit for not getting the perfect hot water in your shower.

Its main job is mixing cold and hot water perfectly to provide hot water with the right temperature.

But if any part of the shower Cartridge is broken or damaged, its functionality will be compromised. This makes the water cold.

If your shower Cartridge is damaged, replace it. But make sure to choose the right size and model. You can contact the shower manufacturer to get the compatible one.

At first, you need to remove the handle located close to the faucet and then take out the attached nut or bonnet from it. Finally, install the new faucet cartridge.

  • Switched Off Water Heater

Test other shower faucets of your house. Are they offering hot water? If not, checking the water heater is essential.

A water heater plays a key role in heating the water entered into your resident. It might be shut down.

So, what can you do in this regard?

Locate the circuit box. The heater might be got off if the circuit switch tagged “water heater” is turned to “Off.”

If this is the cause, switching on the heat is necessary and then waiting for 1-2 hours to give the machine enough time for heating the water. 

Now, you can test out your shower water. Check if the water is hot enough.

  • Dysfunctional Water Heater

If your water heater is switched on but is still offering cold water, the heating component of the water heater might be damaged.

Generally, this heating part works like an oven element, which needs to be replaced after a certain time.

Before replacing this element, make sure you remove water from the heat using a drainage pan or hose. Then disassemble the unit.

Take out the bad element. Finally, install the new part. Now, you can add water inside it.

Since it is a little bit tricky, having some basic plumbing skills is important. Otherwise, hand it over to a professional.

  • Shower Faucet Scald Guards

Some Tuscany shower faucets include a temperature-balanced feature or scald-resistant guards. Its job is to increase or decrease the overall water temperature that comes through the shower faucet.

If a particular shower is not offering an ideal hot water temperature, remove the handle connected with the faucet. You can use the screwdriver to detach the attached screws.

Locate the last part of the faucet with a ring-shaped plastic dial. Generally, it is situated below the handle.

Increasing the water temperature requires you to twist it in a clockwise direction. Keep adjusting it slightly until an ideal water temperature level is achieved and let the hot water pass through the cartridge.

Instead of adjusting the temperature too fast initially, do it gradually. Test how hot the water becomes after each adjustment to avoid overdoing doing.

Once it offers the ideal water temperature, you can now install the faucet handle and head again. Watch this video to understand more about this.

  • Issues with Pressure-Balancing Valve

Does your Tuscany shower faucet feature any pressure-balancing valve, which the main job is stopping any accidental water temperature changes?

Generally, a red lid is visible on the shower cartridge when your Tuscany shower faucet has a pressure-balancing valve.

At first, we need to keep the cartridge inside the cartridge cover, adjust the pressure-balancing valve, and finally change the bonnet nut.

Now, take off the red cap. Rotate the cartridge in a Counterclockwise direction. This will let higher temperature hot water enter inside the valve. But if you have overdone it, rotate it clockwise direction to make the water slightly cooler.

After perfect adjustment, place back the red cap in its original location to secure the current adjustment. Also, attach the shower faucet cartridge to the right location using the bonnet screw.

Turn on the waterline and see if you have enough hot water from your Tuscany shower faucet or require further adjustment.

  • Small Heater Size

Most of our households have around 50-gallon water heaters. So, you have the accessibility of using 50-gallon of hot water readily before processing additional hot water.

The water flow rate of your household showerheads vary, which can be anywhere from 2 to 14 gallons of water every minute. However, water usage per minute will increase if your shower has several sources, such as double showerheads or body sprays.

If your showerhead offers 2 gallons of water each minute, you can get 25 minutes of continuous hot water before the heater tank becomes empty.

However, when hot water is getting through multiple showerheads or other sources, it won’t be possible to get constant hot water after a certain.

The same problem can arise if the showerheads pump water at a higher speed. You will be out of hot water within a short time. The showerhead will offer lukewarm water until the water is heated enough.

When you have a big family, installing a larger water heater is better to avoid running hot water in the middle of the showering.

Alternatively, you can install a showerhead that pumps a reduced amount of water per minute, which will lessen the water usage and the monthly electricity bill as well.

Frequently Asked Question (FAQ)

How do you adjust the temperature on a Tuscany shower valve?

Since we every day use our shower, it is important to keep it well-functional. Make sure to clean your Tuscany shower faucet regularly to prevent mineral buildup. 

Also, replace it every few years when it is not offering the ideal hot water.
