what is it in the pic?

I saw two little thing(circle in red) at the end of the pump from azian_kicker's thread. What are they? Are they using for siphon?

At first I thought it was a check valve? but I don't know now............
it might be some kind of flow meter because it's clear?

Looks like a check valve to me, prevents water from flowing th eopposite direction

Agreed check valve. but they have the other 2 white one on it,

Hmm yeah that is odd, double check valve for some reason? I know you need a double check for irriagtion tieing into city water supply.

check valve?

 

[dirtbikerider]

maybe the double check valve is used in case the first check valve fails? Not sure either way but its a possibility...? don't flame me if im wrong, im just throwing it out there lol

 

[triply]

fpt makes something like this its called a clear union check valve

 

[epond83]

That would make since, it is the reason irragation has to have a double check, incase one fails. And with one being clear it's easier to see if it gunked up with stuff

A doubble check valve makes some sense but I'm sure if that was the case they would all be the same type. I think it might be a micron filter, that is if thats the return side of the pump.
