Review on Thetford RV Drain Valve Lubricant - Optimal Lubrication for Smooth Drainage - 24oz 15843 by Paul Lewis

Revainrating 1 out of 5

Seal Maintenance

I bought this mainly to keep the seals in my 3 tanks in good condition and to last longer. My black tank does not seal tight and has very little leakage. I hope after using this maybe a few times it will keep the black tank closed.

Pros
  • Absolutely Amazing!
Cons
  • Long delivery time
