First I know how to grow, several systems under my belt, CCH2O surpasses anything I have ever used ..period
I have 5 CCH2O systems -3- 4 sites and -2- 6 sites
LEAKS here is what I found
The systems I bought were used / traded in for larger systems
When I bought them from a dealer, I ordered all new bulkhead seals and had some leak issues
several reasons, first the holes in some... of the buckets were 4" The holes for bulkhead fittings they should be 3 7/8"
1/8" makes a big difference, but can be overcome ... 4" holes are for uniseals, I "believe" correct me if I am wrong.
I had a spare, new bulkhead fitting, no tube, set the bucket on a bench, good light screwed it together and bingo ..
It made sense to me.. it is EXACT or nothing, gonna leak .
I fixed all of leaks, even with the "oversized" holes First follow their instructions, leave nuts loose, slide a piece of 3/4" tubing, we all have a mile of it ...to slightly hold the end of the pipe, connector or manifold up so you are not trying to center it by feel, tighten a little wiggle a little tighten snug and they all... sealed, filled with water set for 2 days not a drop ...
That all said let me note... the wax ring seal is brilliant, love it.
SILICONE... I am retired restoration contractor, go into your bathroom, or any place where silicone has been used
it leaks, may be 2 years but look, around windows, see the little black mold, water has got under it, it will fail, period
ok "can live with that, so scrape it out, now replace it, oh, guess what the new stuff will not bond to the old stuff like you assumed. oh I will use something else, ... you will never, ever get anything to seal or bond to that area again..
I had commercial buildings, hotel lobbies, example, who ran a bead of silicone around base boards and marble floors
It permeates anything, everything, use latex or anything else
