BBP Plumbing Inc
We just finished a very interesting project. We replaced the whole horizontal galvanized water supply piping; we up graded the laundry sink and added the gray box. But the major was that we installed new HALO Defender for the whole house. See the link attached HALO-Defender-Spec.pdf (halowater.com)
Some pictures attached.
