Happy Sunday Folks, I got my SWG yesterday and I'm trying to install it. Having a plumbing problem though.
Attached is a picture of my dilemma. What tool would you use to loosen the fitting circled in red. I'm hoping that the grey pipe to the right of the circle (the part with the "return" label on it) is not part of the valve, as it doesn't look like they've left enough pipe there (white) for me to add a new coupler to.
