FAQ

What is a sink water guard?

A sink water guard is a rim or barrier installed around the sink to prevent water from splashing over the edges and causing leaks or water damage.

Can I use regular silicone instead of plumber's putty?

Yes, regular silicone sealant can be used, but plumber's putty is preferred for its flexibility and ease of removal if adjustments are needed.

How do I know if my water pressure is too high?

High water pressure can be identified by a pressure gauge or if you notice excessive splashing, noisy pipes, or leaks.

How often should I check my sink water guard?

Inspect your sink water guard every few months for signs of wear, cracks, or misalignment to prevent water damage.

Can a clogged drain cause water to splash over the guard?
