Dual Flush Toilets-Who’s Afraid of a Streaky Bowl?
Often when discussing low flow toilets or dual flush toilets, the issue most people have, is claiming that it is necessary to clean the bowl more often. While its true in some instances that this could be the case with a one piece, brand new dual flush toilet, is it always the case?
Newer model dual flush toilets have come a long way in terms of design. Steeper bowl sides and improved flow designs have eliminated many of the past bowl-streaking transgressions that plagued the genre. However there is one kind of dual flush toilet that never streaks more than a non-dual flush version. What Im referring to here is a dual flush retrofit kit.
Dual flush retrofit kits convert your existing toilet tank into a dual flush system. The idea behind a dual flush system in the first place is to utilize a full flush for solid waste and a reduced flush for liquid waste. Now, if you have a low-flow toilet already, your full flush is using about 1.6 gallons per flush, or 6 liters. I dont hear many people complaining about low flow toilet streaking. If your low-flow toilet was converted to a dual flush system using a retrofit kit, guess how many gallons of water you will be using for solid waste? Thats right, the same 1.6 gallons. Its only when using a half flush, 1 gallon only, that the water flow changes at all. This holds true for any size tank, the reduced flush will always be 1 gallon and the full tank is the full flush.
So what weve learned here, is that while buying a new dual flush toilet, depending on the model and manufacturer, might leave you with a streaky bowl, converting your existing toilet to a dual flush system never will. If it does, you already had a streaky bowl problem to begin with and it might be time to break out the rubber gloves.
