Many Grand Unified Theories predict processes that would allow baryons to decay to leptons,
violating baryon number conservation and subsequently allowing for both protons and neutrons
to decay through non-Standard Model interactions. Distinct from the high energy decay modes that
very large water Cherenkov detectors are designed to look for are so-called invisible
decays which are only detectable through their subsequent nuclear deexcitations. The SNO+
experiment is uniquely sensitive to this mode of decay due to its low energy threshold,
low background radiation, and detector depth. Presented here are updated results using
a second dataset which triples the total livetime with nearly 200 days of very low background.
SNO+ presents phase II water results on a search for invisible modes of nucleon decay.
