This weekend I installed a HydroRight dual flush converter on our upstairs toilet. As the toilet is an old one and had a ballcock, I also installed a HydroClean Fill Valve which regulates how much water is returned to the bowl after the flush. There is so much talk of water conservation and dual flush toilets, however, the marginal price of water in most communities precludes the feasibility of replacing your whole toilet for s few less litres per flush. For a tenth of the price of a new toilet, you can reduce your water consumption easily with these products and they can be installed without any special tools or knowledge of plumbing.
This is a high quality product that is simple to install and has a lower lifecycle cost than replacing a whole toilet. If it ain’t broke, don’t trash it, just upgrade the working parts.
If you are in Canada, this is available at most Canadian Tire stores across the country.
