PlumbingInstallation & Assembly2MildPlumber$ implied
Lack of space inside a steel stud wall for standard sanitary tee fittings when installing back-to-back sink drains requires use of double wye fittings, causing uncertainty about code compliance and optimal layout.
No low-profile alternative to double wyes for tight wall spaces is available or known, forcing reliance on potentially non-optimal fittings.
