Toto is a good brand. Same as Kolher. I think it may be installation issue or Hong Kong use salt water to flush. I have Kolher shower and it started to leak after amazing 28+ years. I called Kohler and they sent me the replacement parts - free, the part was Lifetime Warranty. Thanks for the video. 👍 Notes: With water shortage everywhere, using salt water to flush toilet is such a good idea.
Thanks for your informative clip. Just want you to add "sea water submersion" sealant like plastic steel putty at the two stainless steel bolt heads to prevent them from rusting towards leaking. Do not use silicone or even MS polymer sealants as their datasheets often say "prolonged water submersion" is a limitation of their waterproof sealants.
