If you notice that the Thread or Water pipe doesn’t match the toilet fittings during installation, this is typically due to the existing wall-mounted angle valve not being removed.
Here’s the solutions:
Solution 1–Try replacing the old valve with the one we included — that usually solves the problem.
Solution 2–If removing the old angle valve isn’t possible, no worries at all — we’d be happy to send you a brass adapter to help complete the installation. Here’s a reference video you can check out. And if you need any help, feel free to reach out to us anytime:
