Water Manifold Repair - Part ID Assistance

[rmcderm313]

Hi All,

I've got a 2009 ThermoSpa that developed a leak last week.  I've identified the source and it is a water manifold.  It appears to be leaking from the dead-end (I have some questions about how it may have happened, but I'll post those in a separate thread).

I'm having trouble figuring out what parts to order to make this repair.  The pipe that leads from the pump to the manifold is 1.5" but most if not all water manifolds I'm finding have 2" slip connections.  I've included a bunch of pictures with caliper measurements in the hope that someone can help me find the correct parts. I'm speculating that somewhere around the 45' angle there is a 1.5" to 2" converter and the manifold is actually 2", but not really sure.

I'm pretty sure the barbs on the manifold need to be 3/4" based on the 1" OD of the hoses.  This seems to be pretty standard.

Any guidance to the correct parts would be very appreciated.  My plan is to cut the 1.5" pipe and make the repair from there with an extension and slip.

Thanks,

Rob
