We are living in our 5th wheel while having a home built. We discovered our black tank valve leaked when we went to dump it after 2 weeks, and now we have major build-up. We can only use our tank about 3 days and it's full. Will RidEx break down all the solids that has apparently settled in the bottom of the tank. We have tried back flushing for long periods of time but that doesn't seem to help. Any help will be appreciated.
To begin with either fix the valve or go to WalMart and buy an external valve to put on the end of the line. Remember from that point on everything will be held back (even the washer.)
Next I would call a mobile RV service. They see this all the time from those that spend any length of time in their rigs. They'll have a pex tube that they'll fish down in there and blast the stuff apart. Good news is you caught it in time and should be a fairly easy job for them.
