K.Kergan :

Hi, my name is Kerry


Is that riser warmer than the othersÉ

K.Kergan :

É

K.Kergan :

The raw water outlets in the riser may be getting clogged with rust scale from inside the riser or manifold.


 

K.Kergan :

If the water flow is restricted it moves through the exhaust maniflod and riser slower so it gets hotter. The most common place for them to clog is in the riser. If it's not too rusty, a good cleaning is all it needs.


 

K.Kergan :

If that riser is warmer than the others, then it's getting clogged.


 

K.Kergan :

The white smoke is likely steam.
