Hello all. I bought a lid for my cold water storage tank, however the existing 22mm expansion pipe (over it) needs now to be routed through the lid. My question is, will installing a 22mm compression flanged tank connector into the lid and connecting to it do the job, or will water from the expansion pipe when passing through the flanged tank connector potentially run down the underside of the lid and out over the sides of the tank? Apologies if this is a stupid question, i'm no plumber obviously.
Cheers in advance!

Just drill a 24mm hole in the lid, about 100mm back towards the riser direction, and bend the pipe by hand until its 1 or 2 cm below the lid.

The expansion pipe will shake violently and spray everywhere. Definitely add it the pipe so it goes into the lid but not long enough to touch the water in the tank
