How to Unclog Your RV Black Water Tank Yourself

The fact of the matter is, a majority of clogged toilets are from pyramid plugs. With that in mind, we can start to solve the problem at hand.

What you need to do is knock out the base of the pyramid. As soon as you do, the pyramid will collapse into your tank bottom - and if you do it correctly - will flow out of the tank and into the sewer and that will be the last of your worries.

The waste digesters inside Unique Holding Tank Cleaner are the strongest, most effective digesters available in any formula on the market. Simply put, if Unique Holding Tank Cleaner can't solve your pyramid plug, then no other product will.

After effectively treating your tank with Unique Holding Tank Cleaner and knocking out the base of the pyramid pug you will be able to empty your tank by simply opening your valve and allowing your tank to drain.

Unique Holding Tank Cleaner is a great way to open a clogged holding tank instead of going through the hassle of hauling your rig into a dealership or repair shop where they will charge you $100 - $200 to clean your tank.

Here's how easy it is...

  2. If possible, add several gallons of water to your black tank. The more water the better, so fill your holding tank up as much as you can without making a mess.
  3. Pour the entire bottle of Unique Holding Tank Cleaner into the tank through the toilet.
  4. Let sit for 12 hours (or more if your problem is extreme). After the treatment period, the solids in your holding tank should be broken up and liquified.
  5. Open your black tank valve and let the tank empty out.
  6. If you have a tank rinser, run it for about 20 minutes to do a thorough rinsing of the tank.
  7. CLOSE YOUR BLACK TANK VALVE and only open it when you're dumping.
  8. Enjoy your unclogged RV toilet!

    How Did My RV Toilet Get Clogged?

    For the majority of RVers, most clogs come from a number of common issues including:

    • A leaky or black tank valve that has been left open
    • A used RV that wasn't maintained correctly
    • Not using enough water when flushing your RV toilet
    • Using Holding Tank Treatments that don't break down waste
    • Storing an RV for an extended time with full holding tanks
    • Excessive toilet paper use

    Each of these issues can easily lead to a backed up tank or a nasty thing known as a "pyramid plug". 

    Often, people make the mistake of thinking that when their black tank is clogged, it is also completely full, which may be the case. However, holding tanks are almost aways flat on the bottom and as you use your RV toilet, waste build up can create a "pyramid of poop" if tank liquids are allowed to drain out from a valve that has been left open. This is probably the most common reason why a tank will get clogged, and is easily avoidable if you follow Rule #1: KEEP YOUR BLACK TANK CLOSED

    Keeping your valve closed is incredibly important, hence why it's Rule #1. 90% of all clogs can be avoided by keeping your black tank closed.

    Because proper black tank care requires keeping your valve closed, your physical and liquid waste will remain in solution inside the tank, which is also why it is very important to use a high-quality waste digester. Without using a quality RV tank treatment and digester, it is more likely you will suffer from constant clogs and build-up. Many popular RV toilet chemicals are designed to encapsulate and preserve your solid waste in an attempt to control odors. 

    You can clearly see how easy it is to get a clog when using the wrong RV toilet chemical.

    NOTE: If your tank is so full that you can not add any water to the tank you can skip adding water to the tank, but please note that for Unique Tank Cleaner to work it needs liquid to nourish the active cultures that digest the waste. So, getting as much water in the tank as you can is incredibly beneficial.

    ALSO NOTE: Sometimes a clogged holding tank may need extended time to unclog your compacted tank or additional treatments. Allow ample time for Unique Holding Tank Cleaner to work and clear your clogged lines.
