Install ABS Drain Pipes using Solvent Weld

What happens here

The existing drain access valve is cut off using a reciprocating saw and replaced with a new system. Black ABS pipes are cut to size using a circular saw. For connecting ABS pipes, special ABS adhesive cement is applied to both the outside of the pipe end and the inside of the fitting. The pipe is then quickly inserted into the fitting with a slight twist to ensure even adhesive distribution and a secure bond. A P-trap and an Air Admittance Valve (AAV) are incorporated into the system. The AAV allows air into the drain system to prevent siphoning of the P-trap (which would allow sewer gases to enter the house) without needing to be vented through the roof. Per code, the AAV must be a minimum of 4 inches above the horizontal drain tube at its highest point. The entire drain assembly is temporarily dry-fitted to confirm proper alignment and slope before final cementing.

Goal: Cut and connect black ABS drain pipes and fittings to create the drainage system for the new sink, using ABS solvent cement for strong, leak-proof joints, and incorporate an AAV valve for proper venting.
