As low-flow toilets are becoming increasingly popular in the Myrtle Beach residential plumbing market, industry professionals are quietly questioning the wisdom of decreasing the volume of water in drains. In some areas, there have been rumblings that the low-flow fixtures in commercial buildings are causing more frequent drain blockages. If there is not enough water to move the solids through to the main sewer, the solids will accumulate in the line causing a back-up.
Industry professionals acknowledge there is a tipping point at which drains will not flow. However, there is no agreement on what that amount is. We had the three gallon flush, then the 1.6 gallon flush, and now we are seeing the 1.28 flush. Fogarty & Fogarty Plumbing agrees that water conservation is an important issue, but we are concerned that studies are being conducted after the fact.
In most homes, adding a low-flow toilet should not cause any problems. If you are in an older home, or have longer drain runs, you may want to speak with a professional plumber prior to purchasing low-flow fixtures.
