Hey all, my dad and I just finished fitting and assembling a barrel sealing piston valve in a tee (We have not glued it yet). The piston is vary stiff and at low pressure will not seal. Is this normal or do we need to slick thing up a little?
thanks

It should move with very little force.
White grease or Vasoliene will solve your problem.

1000 posts of mostly spam :roll: and yeah lard will help with it and if it still leaks you might need to use another rubber thing for it to seal.
