We have 1000’s of MHP sub-meter installs;
For longevity only use sub-meters that are:
- AWA RATED,
- Exterior PIT RATED,
- POSITIVE DISPLACEMENT METER. (allows for vertical or horizontal install, along with other benefits)
The existing galvanized pipe is treacherous , maybe wise replace at the least, the exposed piping into PVC or a PLEX type piping.
