Should I install a valve before this pump (picture)?

I did not see a diverter on the suction side. Can you post a picture of that.

The OP may be talking about the flap at the bottom of the skimmer float where you can control flow. It isn't really a diverter and will not completely stop flow from the skimmer.


Also, that may not be a relevant test anyway if the MD is plumbed through the skimmer as it is difficult to separate the two and the MD would naturally have more head loss so would draw in more air even if the leak was not in the MD line.

Actually, the diverter is a tube-like structure that inserts into the skimmer hole. I'll post thumbnail pictures below of the white plastic diverter in my hand and also installed in the bottom of the skimmer.

As shown in my diagram of my previous post (I'll post again), the vertical pipe in the bottom of the skimmer goes down to the main drain, and there is an intersection with a horizontal pipe just below the skimmer that goes to the pump. The 45-degree part of the diverter is at the level of that intersection with the horizontal pipe to the pump, so depending on which direction you have the 45-degree flap aimed, you will get primarily water from below (the main drain) or from above (the skimmer) going to the pump. The diverter can be rotated over a 180-degree range to get what you want. Remember, this is an old pool -- 1977 installation.

Take the diverter out and try running the pump, see what happens.
