Having your house entirely Re-Piped is a big job! The job itself averages from 2-3 days and could be even longer depending on the amount of work required. So why would anyone want to change out the existing water lines anyway? There could be a number of reasons to have a Re-Pipe done. However, there are (3) common scenarios in which you may want to consider having your home re-piped.
#1 if you have Polybutylene Pipe. Polybutylene (or Poly-B) is essentially a time bomb. It slowly begins to decay from the inside out, cracking internally until pinholes are created all throughout the pipe. These pinholes turn in to big problems. While it is possible to cut this section of the pipe out and replace it with another pipe, Polybutylene decays all over, not just in one or two spots. In addition to this, the bad connections used with Polybutylene have been proven to fail. This pipe is so poor there was a class action lawsuit against it. If you have this pipe, you ultimately will have to have a total re-pipe done.
#2 If you have copper pipes and receive your water from a well. Copper pipes are excellent pipes under most circumstances. Typically, they are very durable and will last for many years. Unfortunately, this is not so if your water comes from a well. When water comes from the County, it goes through numerous filters which entirely remove any tonic acid that are harmful to copper. On a well the tonic acid goes straight to your pipe. Even the heartiest filtration systems are unable to remove it. In these instances, the tonic acid draws out the copper minerals in the pipe. Over time pinholes begin to form all throughout your system. As is the case with Poly-B, a whole house re-pipe will need to be done to permanently resolve the problem.
#3 If you have a leak under the slab of your home. In some cases it may be determined that your pipe is leaking but is not accessible to repair because the leak is under the slab. Once verified that the leak is beyond the point of distribution, the best way to correctly resolve the leak is to have the entire house re-piped. By doing so, we are able to bypass the leak and ensure that your pipes are in great condition. While there are companies that will attempt to fix this problem by opening up the slab, we do not recommend going that route. The best case scenario with slab work is a fixed pipe that is, once again, buried under the slab and out of reach. In addition, it is typically a far more difficult experience selling your house down the road. The foundation of the house will be considered compromised once it has been opened up. The worst case would be having to open up multiple sections of slab because either the location of the leak was detected inaccurately or because of multiple leaks in the system.
