Default CPVC manifold for batch sparging

I'm planning on constructing a MT out of a rectangular cooler and I want to make a CPVC manifold instead of a SS braid -- it just seems a little sturdier than a braid. Does a manifold work for batch sparging?

Yes. With a manifold & properly sized slits or holes you will have less chance of channeling your runoff which should result in a slight efficiency boost.

Also, a manifold works better if you decide to delve into fly sparging. I did my first fly sparge on the last batch with a new CPVC manifold and boosted my efficiency from 72-75% to 88%.

Before changing to my keggle system, I had a 50 qt. rectangular cooler with a cpvc manifold and batch sparged. I regularly got 75% eff.
I often wonder now why I conplicated my brew life sometimes. LOL
Cheers

If you want sturdy and simple, you could try a water heater supply braid, only about 12 bucks at HD. I know you want to use a manifold, but I have had good luck w/ the braid and batch sparging.

A manifold will certainly work for batch sparging, good luck and happy brewing!

My CPVC manifold works very well. I batch sparge and get 80% efficiency. It's worth noting that you do not have to glue the pieces together, it makes it easy to take apart and clean after brewing.

Beware. they float! No issues once you get grain in there though.

A manifold will work fine. My experience is that they're no more sturdy than braid and they take longer to produce clear runoff than a braid.

Good to know. I have heard people complain that the dough in sometimes crushes the braid. But it does seem easier than putting a manifold together.

I have used a CPVC manifold (with slits) for a few years now for batch sparging... Works great! I have moved on to copper though...

Not if you use one of these. They are pretty sturdy
