70qt extreme mash tun problems

Yes, you might need to slow down your sparge to make sure you collect enough of your sugars.

Or just batch sparge.

The geometry of this mash tun is not conducive to a good fly sparge. The large surface area, shallow bed is ideal for batch sparge. Fly works much better going down a narrower column of grist, giving a better rinse of the grains and reducing the chance of channeling.

i have the same cooler and had the same problem, always in the 60's even batch sparging. Switch to the stainless steel sleeve that you get off of some plumbing hoses. I use the braiding i got off the hot water tank hose and connected it to the ball valve using a SS worm clamp. Fold and hammer the other end of the braided hose to seal it. I now strictly batch sparge and run between 70-72%.

For fly sparging, make sure you have at least 4" thickness of grain (minimum) and collect runoff for 60 min.

I have a 52 qt Coleman Xtreme mash tun. It works really well with a SS braid at the bottom for batch sparging... Try switching your manifold for a braid and see if that helps.
