I have a persistant water leak from the pipe that feeds the electrical

Despite several attempts at a fix using that yellow expanding foam in a

I'd appreciate advice on thsi one.

Condensation is one thing. In that case where moisture from warm air
condenses in conduit to underground limit switches, etc. I just squirt a
whole tube of silicone rubber up the conduit.

But if you get constant dripping or dribble, you may have a breach in
the conduit that should be fixed.
