My house contains Vanguard tubing. Specifically: Vanguard Thermoguard Portable Tubing 3/4″ (CTS-00) 100PSI @180F / 200PSI @ 73F ASTM D-3309 PB2110 SDR-11-080 01-31-94 B-4-S. Has this product been involved in a re-call or class action suite? If so, where can I go to obtain further information. Thank you.
