Dry Pipe water routing..

[Wavejammer701155]

Hey there i have what i believe is a coffman dry pipe.. bolted up to a 61x with some goodies, stuffed into a pump swapped wavejammer, running dual cooling... my question is water routing.. drew up a little diagram and was wondering what the “?” Fitting line would run.. ive attached a photo of the diagram, pipe, and head im using (westcoast 160psi head with only 1 fitting)
Thanks

I don't know anything about that particular pipe, but most dry pipes have a line going from the center of the belly of the pipe to the stinger (which in your diagram looks like the one you have t-ed to a pisser). Usually that line does not have the t with the pisser, then the question mark would be out of the water jacket to a pisser.

I'm impressed you fit that pipe in a jammer, that will be an interesting ride!

Are you running water IN both ends of the water jacket then all of the water out into the stinger through a flow control valve?

That right there may collapse the inner chamber with pressure spikes.
Best is in at bottom by manifold. Out at end of pipe lower by stinger. Keep upper out going to stinger (that will ensure full fill).

It seemed like weird routing to me!

Thanks it wasn’t easy! With the 144mm pump in there it should really fly

So that silver pipe pic wouldnt be correct?

This is what I've seen on most dry pipes and I think what MTRHEAD is describing.

If you use a flow control valve it would be in the "connect these" line.

Okay awesome.. the the “IN” arrow.. thats in from the pump??

 

[Storbeck]

Some people run into that from the pump, some people run out of the head and into that. I couldn't tell you which is better.

I don't think I have photos of my Speedwerx pipe but if I were to use that silver pipe as a reference, here is how I would have set it up.

Manifold has 2 short hoses either T'd or preferably Y fitted together, the bottom leg of the T goes to pump supply line #1. The short hoses of equal length make a semi-loop to supply both manifold inlets evenly.

The fitting at the bottom of the chamber closest to the manifold gets it's own dedicated hose from the pump on supply line #2. The top hose at the Lord mounts to the stinger fitting, the hose on the side of the chamber close to the stinger is the only dedicated overboard sprayer.
