The water supply pressure is greater than 80 psi. Pressures above 80 psi may void warranties for some appliances such as water heaters or washing machines. Flexible supply lines to washing machines are more likely to burst with higher pressures. Typically the pressure cannot be regulated at the water meter. Recommend having a qualified plumber evaluate and make modifications to reduce the pressure below 80 psi. Installing a pressure reducing valve on the main service pipe is a common solution to this problem. If one exists, then it should be adjusted for lower pressures.
Plumbing supply lines appear to be made of Polybutylene. Polybutylene is a plastic material used extensively during the 1980s and 1990s that has proven to be more prone to leakage than other types of supply piping systems like copper. Recommend reviewing any disclosure statements if available for comments on leaks in the water supply system.
A class action lawsuit has been filed regarding this material that requires the manufacturers to cover piping systems installed between Jan. 1, 1978 through July 31, 1995. For more information on the class action lawsuit, visit http://www.pbpipe.com/index1.htm
