Frequently Asked Questions
How are double sinks plumbed?
When it comes to plumbing a double sink, each basin has its own individual tailpiece which is connected to a sanitary tee. This tee is then directly connected to the P-trap drain, allowing for separate drainage from each basin. Alternatively, a swing tee trap can be used as an alternative method of connecting the double sinks. Regardless of the specific method used, the primary goal is to ensure that both sinks have a separate and proper drainage system in place.
Do you need two water lines for a double sink?
Yes, it is necessary to have two water lines for a double sink. Each sink requires its own dedicated water source to ensure proper functionality. Attempting to operate both sinks with just one water pipe could result in insufficient water pressure and compromised functionality. Therefore, it is advisable to seek assistance from a professional plumbing service if your double sink lacks the necessary water lines.
Does a double vanity need 2 vents?
Yes, a double vanity generally requires two vents, especially if the lavatories are coming up from below. In this case, two Air Admittance Valves (AAVs) would be used to ensure proper ventilation for each lavatory. However, if the lavatories are positioned on either side, a single AAV with a fixture cross can be sufficient. Ultimately, the specific configuration and positioning of the lavatories will determine the number of vents needed for a double vanity.
Can 2 bathroom sinks share the same drain?
Yes, it is possible for two bathroom sinks to share the same drain by replacing the existing sanitary tee on the stack with a double sanitary tee. This type of tee is designed specifically for adjoining bathrooms, allowing each sink to have its own connection to the shared stack. By utilizing this double tee, the sinks’ drainage can be properly directed and merged into the same drain, ensuring an efficient and effective plumbing system.
