Take it loose from the faucet and flip the lever down on the filter in the on position. Take the cap off and remove the filter. Blow hard through it. You should hear a whirling noise of a gear, like a windmill. If not, I use a water dental pic to pulsate into it and clean it out. This is what makes the light work and when flow goes down, the light changes color. It's all mechanical. No battery. Just free up the gear so it turns freely to work the light. If standing in front of a mirror, you can actually see the light come on. PUR doesn't tell you this because they want you to purchase another one.
Question edited for correct spelling of maker 'Noen' to 'Moen'.
'Fix' as in it is leaking? Or tighten it down because it is wobbly, or something completely different?
Well, we can have a one on one seminar by the internet. I've been a pumpman for 20 years. I can share with you my experience (household pumps, suibmersible pumps, turbine pumps, gear pumps, piston pumps, dewatering pumps, mud pumps, trash pumps, mining pumps, solids handling pump, etc....) Just take your pick. Just send in your e-mail for assistance. God bless.
Move the lever or turn the knob. Check the stop tap under the sink. Make sure the faucet control knob or lever is tight, There is normally a removable cover that hides the screw..
Question edited for clarity, full 'make model (what it is)'.
This a Menards special. To remove handles, look for a small hole hidden from the front. They take a small Allen Key.
air will not be trapped in the pump. what you have to do is prime the pump so that the vacuum is filled with water
the vacuum is created by expelling water which in turn sucks in more water and so on. if the pump is full of air ,there is nothing to expel and so no water is sucked up
there should be a plug at the top of the pump for the purpose of priming. remove it , fill the pump and suction line and replace the plug
