Hot side of exhaust of an Atomic 4

[DougBaker]

Looking for feedback. Just rebuilt the hot side of the exhaust and ended up with water trying to bubble out of the 90 angle above where the water goes into the exhaust to cool it before going into the water lift muffler. The water enters about 4" below the 90 angle and aprox 9" above the muffler. I do have a siphon break air valve installed, that may not be installed correctly. On my way to check it, any other suggestions out there that I should check. Last physics class I toook said water can't flow up, especially with exhaust going in the opposit direction.
Thanks
Doug

Thanks

Moyer did confirm my fears that back pressure is the cause. Which means replacing the cold side of the exhaust hose.
