Ok right, can someone check this hosing? Especially what I've circled in red. At the top, why do I only have 1 nipple when all the diagrams show two? (one coming from the bottom red circled nip and then the missing nip going to the left most red circled nip)
Is how it's currently connected up ok? Do I need to cap off the other two nipples or connect them altogether?
Pic of how it is:
