I have searched on this topic and haven't found a answer as to how to fix/live with it so hopefully you can give some more info. I have installed a rola chem 12gpd pump with 15 gallon tank. I have only had it up and running about a week. When I first installed it I placed it on the equipment pad outside where it gets afternoon sun. I found that the 10% bleach was off gassing in the clear nylon lines causing bubbles in the lines. eventually it would off gas so much that there would be a large portion of the line without liquid and if left alone I assume the entire line would be without any liquid and would run dry. I didn't like having the chlorine exposed to the sun especially with the clear lines and found that the off gassing was worse as the solution got warmer, so I elected to move the pump and chlorine tank inside (luckily the equipment pad shares an exterior wall with my garage). So the tank and the pump are currently mounted inside the garage and the feed line runs through a small hole in the wall outside to the port in the return side of plumbing. outside I have sleeved the clear nylon tubing with an opaque tubing to shield it from he sun. after moving the pump/tank inside it is in shade all day and has reduced the amount of off gassing considerably. however, after a few days all the small bubbles find their way to the highest point which is the pump and sit there. basically, it has just reduced the amount of off gassing so it will take longer for the tubing to fill with air but hasn't fixed the problem. so, my questions :
is there any way to prevent this from happening?
will this cause a problem if left alone?
if the bubbles get injected into the pool will they still be sanitizing? (are these bubbles chlorine gas or is it just air?)
what can be done to improve the performance of this system?
appears that stenners come with black tubing so perhaps there are bubbles in these lines as well that users are just unaware of?
Thanks in advance!
