For about a week or so I had low cold water pressure in half of my condo. Checked the meter and discovered a leak at the PRV. The PRV was replaced but I continue to have low cold water pressure in one half of my condo. I also was told my place was piped in polybutelene. Could the PB piping cause water pressure problems? Please advise.

If your hot water pressure is better than your cold, then there is nothing wrong with the meter and water service. This will also depend on if the system was piped as a home run system or piped in branches. If it is a home run system (all of the pipes individually run back to a manafold) then there could be something wrong with the manafold. If the piping is branched, then I would start with all of my aerators and shower heads to see if they aren't blocked. If they are fine, then I would remove a supply tube from one of the sinks and check the volume coming out the cold water supply by diverting it into a bucket. This will tell you if its the faucets or if itsw the piping itself.

Write back and let me know.
