Hey, noob here. SWIM's going through Vovin's Tek for the first time and everything is going well UNTIL step 5: Basification.

SWIM's supposed to achieve a pH level of 12-13. SWIM starts adding lye to 200 mL of warm distilled water and the @%$&%^@& pH approaches 11.8 and then starts to become more acidic as SWIM adds more lye. WTF!?!?! What is SWIM doing wrong? SWIM even ran out and got new buffer solutions to recalibrate SWIM's pH meter (which is brand new) in case SWIM contaminated them, but SWIM still gets the same result after recalibration.

SWIM's Lye base solution is only 11.5 and decreasing. Is there a threshold for lye absorption in water? SWIM has no idea.
A little help here, SWIM's stuck

EDIT: SWIM is using Roebic Drain Opener 100% lye and a cheap Hannah pH meter.
