Cold water side is not working suddenly. All water is on.

Cold water side is not working suddenly. All water is on.

Shut the water off And open up the valve. Remove the cartridge and check and clear any trash in the inlet ports. Now turn the water back on for a moment to flush out the supplies. Reassemble and test. Better now? Good luck. Tom

Thank you for your reply. I am a true amateur. Is the valve the handle? Is that easy to take off? I assume I will need correct wrench... working on that now.

If you need a step by step I'll need the model number, The valve isn't the handle the valve's the facet itself. Have you anyone that could help you? Back to you, Tom

I went to Home Depot and they showed me on the floor model. There is a cap in the back to pop and I will use an Allen wrench. I still have to do. I appreciate your help . I'm trying to fix myself. A plumber is $65 to walk in the door.

I could do a lot better if I had a drawing or model number so we could take your faucet apart and flush out the pipes. Is there a male friend or neighbor just in case things get wet or dirty? Regards, Tom

Will have to work on later. No help here. I'm back to busy schedule. I will post when I take off cap and Allen wrench. Thanks for your help. I truly appreciate Tom.
