New Attachments - Greater Capability
|
|
Mazco has expanded the Safe-T-Stopper capability to service and remove street type threaded tees up to 2”. A new lower housing and main seal allows for the street tees to be unthreaded from the cast iron or steel mains and a plug threaded in its place. We can even put in a new threaded tee and sch 80 pipe nipple in place of the old tee. Upgrading and insertions of service lines can be done safely and cost effectively. |
