Thank you for letting the PlumbersStock team help! With regard to your problem, there could be several reasons why you are not getting cold water. It is most likely because of a defective pressure balancing spool. The pressure balancing spool is part of the cartridge in your shower faucet, which means, your shower cartridge may need to be replaced. If your shower valve is still under warranty, you may contact Moen at 852 2506 0670 for a possible replacement. Thank you for visiting PlumbersStock.com!
