As a homeowner, one of the main concerns you might have about CIPP, is in regard to water flow. The idea of making a new pipe inside of your current pipe leads to questions about losing water flow. Will you still have adequate water pressure? Will it take longer to fill a pot full of water for pasta? The good news is that CIPP doesn’t reduce water flow much. In some cases, water flow actually increases once new pipes are in place.
CIPP IS ONLY SLIGHTLY SMALLER THAN YOUR ORIGINAL PIPE
Yes, cured in place pipe repair does reduce the diameter of your pipe. The liner itself has a thickness. Additionally, the resin that it carries hardens into the pipe that carries your water. The difference in diameter between the liner and the original pipe is distinct, but typically not enough that you notice a difference in your water pressure. Your showers should be just as strong as they previously were. The difference in water quantity won’t be noticeably weaker. In some cases, it may even be stronger.
CIPP CAN STOP WATER LOSS AND INCREASE FLOW
Most pipes aren’t replaced until something drastic happened. Replacing a long pipe with CIPP not only addresses the crisis issue, but addresses other issues as well. Many pipe disasters begin as slow leaks. Typically, a damaged pipe might develop several sources of water loss before repairs are made. CIPP seamlessly joins to the pipe. It repairs not only the major issue that caused the replacement, but also repairs any unknown minor leaks as well. Stopping the water loss results in a stronger water flow than you’ve had in quite a while. In cases where pipes were breaking down from old age or lack of maintenance, you're likely to notice an uptick in water flow.
WHAT CONTROLS THE THICKNESS OF CIPP LINERS
The thickness of your CIPP liner depends on several factors. The liner, along with the resin that CIPP repair depends on, will vary in thickness depending on the ovality, length, depth, and diameter of the pipe that it's lining. In general, the more oval your pipe, that is, the closer the original pipe is to buckling, the thicker your liner will have to be. Additionally, a larger pipe needs a thicker liner. The deeper the pipe is buried, the greater the load that the pipe will have to handle. If a liner is too thin, it will collapse before the resin is cured. The minimum thickness of a project’s liner depends on a professional assessment of all of these factors. However, as the thickness of the liner corresponds to the size of the pipe that it’s lining, the proportional thickness of the liner remains very thin.
In summary, CIPP does not reduce water flow in any meaningful way. In fact, in some cases CIPP increases water flow that you may not know was missing. Blocking out a lot of small, unnoticed leaks adds up to a greater water flow. How thick your CIPP liner will be, depends on a variety of factors that your CIPP contractor can determine upon inspection.
