Payback Period for Low Flow Toilets: Is the Cost Offset by the Water Savings?
Water Saving Toilet vs. Regular Toilets
If you’re looking for the best of both worlds – environmentally friendly without a changed experience, then a water efficient toilet may be ideal for you. Water efficient toilets use roughly 1.28 gallons per flush whereas older toilets can use up to 7 gallons of water with every flush. Federal plumbing standards now specify that new toilets can only use up to 1.6 gallons per flush.
High-efficiency toilets of today surpass traditional toilets in terms of efficiency, lifespan, and power. You will not have to suffer multiple flushes and low-flow cleaning issues if you make the switch to a high-efficiency design today.
Also, there isn’t a need to run out and buy a new high-efficiency toilet. Often times it is more cost effective to simply retrofit the toilet than purchase a new toilet. When you consider that your toilet may be flushed as much as 5 times per day you can easily use 15-35 gallons of water per day! As you can see below the water usage of an older toilet can add up.
TOILET CONSUMPTION AVG. FLUSHES PER DAY EST. GALLONS USED PER PERSON PER YEAR
7 GPF 5* 12,775
5 GPF 5* 9,125
3.5 GPF 5* 6,388
1.6 GPF 5* 2,920
1.28 GPF 5* 2,336
Now imagine for a minute you have a family of 5 and multiple those above figures and just look at the water usage in the bathroom! That’s why we say at Water Saver if you want to practice water conservation then you need to start in the bathroom.
How to Determine if Your Ticket is a Low Flow Fixture
Put down the seat and check for the flush volume stamp between the seat and tank. If the stamp reads “1.6 gpf or 1.28 gpf,” your toilet is already a low-flow model.
Take off the lid and check for a flush volume stamp or a date stamp inside the tank. The stamp may be on the walls of the tank or on the lid itself. Look for model numbers and brands, you may be able to find it online.
The date is generally the month and year it was produced and the number, if followed by L, represents liters of water used with each flush. Based on the year, the toilet uses the following gallons of water per flush (gpf).
Before 1985: 5 to 7 gpf (gallons); 18.93 – 26.5 liters
1985 -1994: 3.5 gpf; 13.25 liters
After 1994: 1.6 gpf (excluding Lamosa)
Mandatory January 1, 2016: All toilets sold or installed in California must be 1.28 GPF or less
Essentially, if you don’t have a high-efficiency toilet you may be flushing money down the proverbial toilet. But fear not you don’t have to run off a buy a new toilet. You can purchase a dual flush toilet retrofit kit to help you reduce your monthly water bills and conserve water within your home.
In addition, the payback time for a conversion kit is dramatically shorter than purchasing a new high-efficiency toilet. Especially if you consider the payback period ranges from half a year to several years depending.
In conclusion, if you want to conserve water it’s best to start in the bathroom with a new WaterSense toilet*. Call Mike at 419.349.4700 for a free estimate or fill out a form for request information
