I believe I have a Aquasource Glyndon 873-3727h2. The issue I'm having is no cold water comes out, on this shower only. My other shower works perfectly fine. I purchased this house used, it's 10 years old. I've replaced the cartridge twice. I've tried blowing air through the shower head and tub spout. I've tried running the cold set screw in and out. I have scoured the internet and YouTube. I've been trying to get my guest shower ready for Thanksgiving, as we are hosting our family this year. Also this past February, our pipes froze through the house, and caused other faucets to get clogged. I had to remove the screens to fix the issue. I thought this one had the same issue, but it didn't. Any other suggestions?
