tank remodeling,sump question? (last page)

[jjntm]

I am a plumber... and I can tell you that primer is only meant to clean the pipe before applying the cement... It is not needed under such low pressure systems like our aquariums. I have used the spa flex well for my 220 gal tank upgrade and never used primer and have no issue's... The one thing about the spa flex to make you aware of... for the first month or so the flex line is almost slimy, but does not affect the water quality... if you have any questions feel free to pm me
