"We have had very low water pressure for years. When I asked Paul to come out to look at our water system. He pointed out where potential problem areas were and recommended a solution. To make a long story short, we now have fantastic water pressure in all areas of the home and the water is silky soft. Paul showed up at the time he said he would, was done quicker then expected and explained how everything would work. Great experience!"

No Hot Water? Here Are the Top 5 Causes 


Once you discover you have no hot water, it's important to pinpoint the cause. You don't want to be stuck unable to bathe or properly do the dishes and launder your clothes for too long. To help you find the reason why your hot water may have disappeared, here's our list of the top 5 causes of no hot water in the home.

 

1. Blown fuse


A lack of hot water might be the result of a blown fuse or tripped breaker that has caused your heater to shut down. In most cases, resetting the breaker will be enough to get it up and running. If this is happening a lot, however, it might be worth replacing the breaker or fuse with a higher amperage unit. 


In the event of a short in the wiring, that will not only prevent the heater from functioning properly, it's also a serious fire hazard. Be sure to check all wires for signs of damage and replace as needed.

2. Supply vs. Demand

One of the most common issues is quite simply an empty hot water tank. Using too much hot water in a short period of time will empty the tank’s supply faster than the heating elements can replace it. 

Most tanks require half an hour to build up a sufficient supply once drained, so you'll be left with nothing but cold water in the meantime.

If this is a frequent occurrence, you may want to consider upgrading to a larger heater. Water heaters are often installed based on an estimate of the demand for the current residents.

Circumstances change, and you should make sure your heater is equipped to meet the currents demand of your household.

 

3. Leaking Hot Water Tank

Most of the time, a leaky hot water tank is caused by faulty connections or valves. If not properly addressed, this small nuisance can quickly turn into a major problem, namely serious flooding and water damage. Be very careful when checking for leaks because the water here may still be hot, despite it not reaching the upper levels of your home.

If you have a leaking hot water tank, call a plumber immediately.

 

4. Broken dip tube

The dip tube is where incoming cold water enters the water heater tank. If functioning properly, the dip tube shoots cold water to the bottom of the tank where it can be quickly and easily heated. A broken dip tube leaves water at the top of the tank, where the outlet for hot water also resides.

A broken dip tube, therefore, might mean cold water is being poured into your home’s hot water pipes before being adequately heated.

It's best to call a plumber to deal with this one!

5. Sediment buildup

Water that enters your heater tank often carries dissolved minerals, small amounts of sand, and other debris - especially in Kitchener-Waterloo and surrounding areas, where the water is especially hard.

While the water sits in and is heated by your water heater, this debris settles to the bottom of the tank. Since most water heater burners are at the bottom of the tank, a buildup of debris can make your water heater less effective. 

Note: This issue is often accompanied by a pinging sound.
