- Water Ridge dual flush from Costco Hi, I recently saw a 'Water Ridge' dual flush toilet from Costco selling for $200. Everything comes in one box, including wax ring and seat. Does anybody know who manufactures this toilet? Seems like a great price for a dual-flush, but I'm not going to buy if it doesn't flush well.

Purchased 5 dual flush WaterRidge toilets from Costco 7 years ago. They all worked well until few months ago when two of them started to leak and generate quite loud fluttering noise. I adjusted the height of the plungers which appeared to solve the problem for a short while. Them I removed the central column to check the 3” seal. Both exhibited swelling about twice the thickness of the rubber seal and over 1/4 of the circumference.
The only difference between those two toilets et the 3 other we have in the house is that few months ago we started to use CLOROX tablets to remove lime deposit in the bowl.
CLOROX is BLEACH and bleach is SODIUM HYPOCHLORITE. I am convinced that a chemical reaction is taking place as rubber compounds such as SBR, NITRILE & NEOPRENE for instance are NOT COMPATIBLE with HYPOCLOROUS ACIDE.
I reached to Globeunion their customer service and they were kind enough to send me new seals. They solved the problem. In the meantime the two swollen seals that I had cleaned up and put aside had come back to their original dimensions.
I wanted to relate my observations to the design and chemical engineers from WaterRidge but was told that their “design team is based out of our international HQ in Taiwan”, and I guess that wanted to leave it at that.
I would have strongly suggested them to re-asses whatever rubber compound material they use with CLOROX. They wanted me to return the defective parts, but as I said they came back to their original state.
My posting could have been more technical and if it is still confusing, i suggest NOT to USE CLOROX IN YOUR TOILET BOWL.
Oh, by the way next time you design a molded seal, do not put the cavity number of the mold close to where the valve seats.
