Why not use glue to secure the riser / cleanout pipes?
Glue holds the riser/cleanout pipe rigid at the connection, The “A” Clamp allows for some lateral movement but absolutely no vertical movement. It is the vertical movement that is the problem. Because the glue holds the pipe rigidly it can and does lead to the pipe cracking and leaking. Also the Aclamp can handle up to 1600 pounds of vertical lift while the glue can handle only 65 pounds of vertical lift. We don’t use traps , we only use clean outs. There is a version of The “A” Clamp that secures riser / cleanout pipes to laterals in cases where traps are not used. What costs are we paying right now? At this time in order for the wastewater treatment plant to handle the extra flow you are paying for extra electricity to run the pumps, increased frequency for maintenance of the pumps, extra overtime to monitor the pumps and extra chemicals to treat the fresh water flowing into the system.
