I have an inline chlorinator. I believe it’s supposed to fill (at least somewhat) with water. It appears mine doesn’t fill at all. The water flows in, but maintains zero water level within the column. I tried increasing the flow and the pump speed but it didn’t change anything. How can I fix this? IMG_1973.jpeg

The manual (Powerclean Chlorinator Instructions - CMP Pool Products) says that 3-5" of water inside is normal operation.
There is a warning about a 90 bend being too close to it, that can interfere with filling and operation. Unclear whether yours is suffering from that issue due to the valve, or not.

After 30+ years as a tablet guy, and dealing with MANY chlorinators - the best possible advice I have is to take it out and throw it away. Start reading up on Salt Water Chlorine Generators. Your chemical costs will drop to very low levels (even after accounting for the initial cost). You will never have to suffer from algae outbreaks caused by the tablets raising your CYA so high, it is impossible to maintain an effective Chlorine level. You will never have to
"shock" the pool. And it will get you off of the drain and replace water roller coaster that the ever increasing CYA levels the tablets cause.
The time you spend feeding and caring for the pool will dramatically drop, too. My several hours a week became 15 min - 1/2 hour per week!

I'm with @sande005 on all comments. I've worked to repair at least 6 or 8 of them, one headache after another. In the end they are just worthless. Even when they work, the expensive trichlor tabs just run the CYA up with all the resultant well known troubles. And so much fun trying to shock a pool with CYA over 70 or 80. Just back up the liquid chlorine tanker to the pool!
 
The only negatives to having one are:
  1. Initial cost (although over the life span, it saves you a GREAT deal of money on chlorine costs).
  2. They stop working in colder temps (<50), so at those times you need to use liquid chlorine. But not much at those temps.
  3. Depending on your other equipment, there might be additional costs to get it to play well with everything else. They should never be operated if there is no water flowing in the plumbing, some systems are plug and play with the pump, some need added components or an external timer to coordinate run times.
  4. You may hear tales from others about corrosion or degrading of stone/masonry. All untrue. The concentration is 1/10th of sea water. Many can't even taste it. Tablets also result in salt being put in the pool - in many cases, it has built up to be almost what is needed for the generator (mine did). So you likely have a salt water pool already. And nobody blames those for corrosion, etc, issues.
