Two years later, 2 of the 3 HydroRight Dual-Flush conversion kits have been removed and replaced by standard flush mechanisms and the third frequently fails to stop running after a #2 flush. I love the concept of the product, but have not had much luck even after talking to their support.
Toilets typically consume 27% of household water usage according to the EPA. For an average family of four that’s 75 gallons of water being flushed down the drain per day, literally. The best thing to do for the environment is to replace older toilets (those manufactured before 1993), which use 3.5-7 gallons per flush (gpf), with modern WaterSense (the H20 equivalent of EnergyStar) toilets that use 1.6 gpf. An even better choice is the dual flush toilets that use only 0.8 gpf for #1 and 1.6 for #2. Replacing a toilet isn’t always practical once you factor in the cost of the toilet and hiring a plumber. Here is how we turned a regular toilet into a water saving dual-flush toilet in just about 30 minutes.
So if you are not interested in spending $300+ per toilet replacing them, but still want to save water with modern dual flush technology, consider getting a conversion kit like the HydroRight Drop-in Dual Flush Converter. As we always recommend, before spending money to convert all of the toilets in your house, buy one and see if it works for the style toilet you have and that you are happy with the solution before investing in the entire upgrade.
Basic Installation Instructions
- Step 1: Gather supplies
- Channel lock pliers or adjustable crescent wrench
- Flat head screw driver (needed for removing this old style flapper valve)
- Old towels or rags (the old rubber and plastic made my hands messy)
- Step 2: Prep the area
- Clear stuff off the back of toilet
- Clear stuff from around the base
- Place old towels under the tank just in case you have leaks
- Step 3: Turn off the water
- Step 4: Empty the holding tank – i.e. flush the toilet
- Step 5: Check manufacture date on tank lid. This one was made on July 28, 1989, which means it is NOT a low flow toilet and uses well more than 3.5 gpf (my guess is 5 gpf)
- Step 6: Disconnect chain and remove flapper valve
- Step 7: Remove handle
- Step 8: Install dual-flush valve (slips on the fill pipe)
- Step 9: Screw on flush button
- Step 10: Connect hose to flusher
- Step 11: Turn water back on
- Step 12: Flush and Adjust (repeat as necessary)
- Step 13: Put everything back
- Step 14: Give quick lesson in how to use
