Save On Water

When you go to flush the toilet again, you should think about exactly how much water you’re using. Chances are that the actual number is a lot higher than you may think. According to research, each and every person uses 100+ litres of water each day–and that’s just when flushing the toilet. Overall, 28% of an individual’s total indoor water use comes from flushing the toilet. Incredibly enough, bathroom water usage (showers, baths, hand washing, and toilet flushing) accounts for 50% the indoor water use for your home. With bathroom water usage representing such a large number of overall water use, it’s even more important to become efficient in the bathroom. Follow Preferred Plumber’s quick and easy tips for increasing your water efficiency in the bathroom.

Here’s How You Can Reduce Your Water Use In The Bathroom


20% of your total indoor water use comes from using the shower or taking a bath. It’s worth mentioning that baths typically make up a pretty small portion of the total water usage, although for those who take baths regularly, the number could be much higher. That’s why it’s important to take a shower instead of a bath whenever it is possible. Showers–particularly quick ones–tend to use significantly less water than baths. However, if you absolutely need to take a bath rather than a shower, make sure your tub is not overfilled. A good rule of thumb is to only use enough water to fill one quarter of the tub.

Having a good shower flow rate is also important for water efficiency. Older shower heads are known to use between 15-30 litres of water per minute, which really adds up over time. When Preferred Plumbing Solutions works on improving your shower’s water efficiency, we check to see that the shower water flow rate is just right. The Ontario plumbing code requires the shower head flow rate to be less than 10 litres per minute to be considered efficient. If your shower head flow rate is more than 10 litres of water used per minute, Preferred Plumbing recommends that the shower head be replaced. Preferred Plumbing can replace the shower head for you at an affordable cost, which will boost your home’s water efficiency.

It’s also worth noting that when you use less water in the shower or bath, you save money on your water bill and also on your hydro or gas bill.

Leaky Faucet


The bathroom faucet represents only a small amount of your overall bathroom water use, but it’s still an area where there’s typically room for improvement. As with the showerhead, it’s important to look at the faucet’s flow rate. A faucet flow rate of under 8.5 litres per minute is considered water efficient and meets Ontario’s plumbing code. If your faucet uses more than 8.5 litres of water per minute, Preferred Plumbing can make your faucet more water efficient by replacing the aerator with a new, more efficient water aerator.

Also, the faucet can waste water if it is allowed to drip. As much as 55 litres of water can be wasted if a faucet is left to drip for 24 hours. If the drip is consistent, this may mean 20,075 litres of water is wasted per year. Preferred Plumbing Solutions can fix a dripping faucet and improve your faucet’s water efficiency.

Use the Flow-Tech water system, it will guarantee you water efficiency.


By far the biggest water waster in the entire house is the toilet. Roughly 1/3 of an individual’s water use comes from flushing the toilet. This is because many older toilets use 13 litres of water with each and every flush.

The easiest way to increase water efficiency in your home (and therefore lower your water bill) is to upgrade to a more efficient toilet. Preferred Plumbing can boost your home’s water efficiency by replacing your toilet with a low-flow or dual-flush model.

The Importance of High Efficiency Toilets

As mentioned, an inefficient toilet can be very costly both in terms of water use and your monthly water bill. This is why we at Preferred Plumbing recommend that you switch to a high efficiency toilet when it comes time to upgrade your old toilet.

However, it’s important to realize that not all high efficiency toilets are created equally. Preferred Plumbing looks closely at the Maximum Performance (MaP) score for the toilet to ensure that we are installing only the highest quality toilets in your home.

Leaky Toilets Equal Waste

You don’t just use water when you flush a toilet—in some cases, your toilet may continue to run after flushing which can result in a lot of water wasted. How much water is wasted when a toilet runs after flushing? It’s estimated that as many as 200,000 litres of water is wasted per year by a toilet that continues to run post-flush. That’s a significant amount of wasted water and will result in a higher bill for you.

Not all leaks can be easily spotted. Some toilet leaks don’t make a sound and aren’t visible to the untrained eye. Preferred Plumbing’s technicians are trained to spot the obvious and less obvious toilet leaks by performing tests to check whether or not a leak exists. If a leak does exist, Preferred Plumbing Solutions can quickly repair it and potentially save you hundreds of dollars in future water bills and repairs.

More Helpful Tips For Your Bathroom

  • Save big money by switching to a new efficient ultra low-flush toilet. By doing so, you’ll use between 50% and 80% less water per flush.
  • Don’t ever flush garbage down the toilet. This can cause a clogged toilet which can affect the toilet’s water efficiency.
  • Quick showers are good. Remember that the longer you shower, the more water you use. Even cutting your shower time down by a minute or two can make a big difference.
  • Smaller baths are also good. Limit filling your tub to a quarter of the tub and you’ll notice a difference in the amount of overall water used.
  • Get more efficient in the shower and in the sink. Preferred Plumbing can replace your showerhead with a new low-flow model and install low flow aerators on your faucets to boost your bathroom’s water efficiency.
  • Practice water efficiency when brushing your teeth, washing your hair, or shaving. Don’t leave the faucet or showerhead on while you’re doing any of these things as a lot of water can be wasted. Fill a glass with water to rinse your mouth and turn the faucet or showerhead off when you’re not actually using the water.
  • Don’t use chlorine pucks in your toilet tank. Although these are typically used for disinfection, they can destroy the rubber and plastic parts in your tank. This, in turn, may cause the flapper break down and cause a leak in the toilet.
