The knob is loose and I need to tighten it. I think the model number is RP28595 from the pictures on the web. Some instructions say to pop the cover off but it will not pop off. I am afraid I will break it.
Hi Bruce, Thank you for your question. To remove the temperatue knob cover on a 17 series faucet you will need to use your fingers to pry apart both sides of the round portion of the cap and then lift up from the bottom to the top to remove. Here is a link to our How to Replace a Delta Tub or Shower Cartridge video.
