Three Overflow Extension Tubes, The extension tubes we make are 25 thousandths of an inch difference in size.
Our tubes raise the level of water in your tank for added water pressure. Just simply slip these over your flapper valve and you will have more powerful flushes instantly. Water pressure helps dictate a toilet’s flushing pressure and these tubes prevent the issue of clogged toilets- very simple.
The tubes we sent you are 8 ½ long and if you can add another inch of water, you will be able to flush about another ½ gallon of water. More important, the longer your inlet valve stays on the more water you will put into your toilet bowl the better the flush. The extension tube is easily sealed with silicone glue. The over flow tube holds the flapper valve and the distance between the flushing handle hole and the top of your overflow tube is the maximum you can improve the fill of your toilet water tank. Our over flow tube extension can only increase the amount of water in your tank by that distance. We can improve the flushing of almost any toilet but that improvement is based on how much more water height can be increased.
