What does this piece of equipment do?

Hello all,

New pool owner here.. purchase a house with a pool and don't have the manuals for the equipment. Been able to find them for the filter and chlorine puck thingy.. :) But there is what looks to be a shutoff valve right before where water enters the pump.. it has 2 pipes going into it (I assume from the skimmer and from the main drain), and has the following markings on it:

R90 L90
180 R90
180 L90

It appears to be set on R90 L90 right now, which I assume that means its draws from both sides equally. The other 2 settings I assume would divert 100% of the return flow to the main drain or skimmer instead of both? There is also an off setting which I assume shuts off all return water from the pool? This device does say 'pentair' on it which is the same as my filter brand.

Hi,

If you don't have a spa with the pool then you're probably right about the valve. A valve in front of the pump controls where the water is pulled from. When you vacuum you want all the water being pulled from the skimmer. Easy to check it out by turning the handle.

If you think it might be something else or want more info on it, post a pic if you can.

Good luck.
