I have a PH of 9.3 SU and a Hardness of 3.6 mg/L. Culligan had installed a chlorine injection & carbon bed to remove the sulfer smell but our plumbing is repeatedly being repaired ( shower valves . Culligan now is recomending a acid injection system to lower the PH and remove suspended sulfer ? any coments ??
