Why Is My Hot Water Not Hot Enough?

Why Is My Hot Water Not Hot Enough?

A common question we get asked this time of year concerning hot water repairs is “Why is my hot water not hot enough?

We find our clients tend to notice this problem predominately when showering and in most instances, the temperature of the water hasn’t suddenly changed. It’s more than when the weather is fresher, and we tend to increase the ratio of hot to cold water, and therefore, any fault that affects the hot water becomes more apparent.

Hot Water Not Hot Enough, Common Causes

When customers ask “why is my hot water not hot enough” we always provide as much information as possible.

In our 42 years of plumbing experience and as hot water specialists, we have found the most common causes of this problem are:

Let’s take a closer look at each of these possible problems.

Malfunctioning tempering valve

Tempering valves are designed to blend hot and cold water to deliver water at a constant temperature that does not exceed 50’C. If water entering the tempering valve contains small amounts of sand or other debris, this can become lodged in the filters of the tempering valve and affect the operation of the valve resulting in lukewarm rather than hot water.  Read more about tempering valves.

Faulty hot water service

If your hot water service is older (usually 10-15 years) or you have overlooked regular maintenance, it could result in a problem with the heating system.

A hot water system fails most commonly at these points:

The element is the mechanism within the hot water service that heats the water with the thermostat being responsible for switching the element on and off. Any problem with either of these parts can result in disruption to your hot water.

The relief valve is responsible for releasing built-up pressure as the water heats. If this valve is continuously leaking, then you will lose hot water which in turn is replaced with cold water that cools the hot water stored in the tank.

Hot water demand exceeds the capacity

Typically if a tanks capacity is over 125L, then you would connect to one of the off-peak tariffs, which means that electricity used by the hot water system will be charged at a lower rate. While this makes for a cost-effective solution, it does come with some limitations as you do not have an unlimited supply and if for any reason your demand for hot water increases there is always the possibility that you could run out of hot water.

If you are finding the hot water in your household is consistently not hot enough, and repairs are not required, then seriously consider a more substantial capacity, new hot water system.

How to check if you have a water pipe leak

With a water pipe leak, it’s commonly said that prevention is the key. Positive preventive maintenance saves you thousands of dollars in hassles and water damage.

That’s why you want to follow the simple step by step check for a water pipe leak. This will prevent the hassles before they hit you where it hurts most – in your pocket!

Step by Step Instructions

Below we run through:

  1. Check your taps
  2. Check your toilets
  3. Turn the taps off
  4. Check your water meter
  5. Wait 15 minutes
  6. Compare water meter readings
  7. Turn the taps back on
  8. When to call a plumber
  9. When your good to go

 

At Whywait Plumbing, we have always preached that preventative maintenance policies and procedures will prevent many of the significant cost blowouts in plumbing maintenance.

As always, prevention on checking for a water leak is the best solution. An underground concealed water pipe leak is often impossible to see or hear. More so if your home is on sandy soil or has lots of garden vegetation.

The simplest way to check if you have a concealed water pipe leak is to follow the how-to steps below:

Step 1 – Check your taps

Check all taps both inside the house and outside the house are not dripping.

Step 2 – Check your toilets

Check the toilet cisterns are not overflowing or running into the toilet bowl by tipping a few drops of food dye into the cistern and if there is no colouring of the water in the toilet bowl you know there is no leak.

 

Step 3 – Turn the taps off

Why Is My Hot Water Not Hot Enough? 3Turn off all the taps that you normally leave turned on, such as the washing machine, dishwasher and the toilet cisterns.

 

Step 4 – Check your water meter

At the council water meter check the meter is not turning and write down the figures on the meter dial.

 

Step 5 – Wait 15 minutes

After 15 minutes recheck the water meter and write down the figures on the meter dial again.

 

Step 6 – Compare water meter readings

Compare the figures you have written down, and if the numbers have not changed at all, then you have no water pipe leak. If the numbers have changed very slightly repeat the test but do it for at least 1 hour.

 

Step 7 – Turn the taps back on

If you are satisfied there are no leaks remember to turn back on the taps you turned off at the washing machine, dishwasher and toilet cisterns.

 

Step 8 – When to call a plumber

Why Is My Hot Water Not Hot Enough? 4If the meter dial reading on the water meter has changed after 1 hour then in all likelihood you have an underground concealed water pipe leak, and you need to give Whywait a call to organise leak detection.

Step 9 – When your good to go

If the meter dial reading has not changed, that means your underground water reticulation piping is in good condition.

Prevention is the key

No matter what your results in the above step by step preventative maintenance suggestions, we recommend you repeat it monthly. We also recommend you record your water meter readings every month as any change in water use patterns will quickly indicate a possible leak.

As a rule of thumb, YOU ARE RESPONSIBLE for any water leak after the council water meter that is on your property. Therefore we recommend that you at least check your water meter reading every month and seriously consider the installation of an AquaTrip water pipe leak detection and control system.
