1. Connect sewer hose to RV park sewer connection with a dip in the hose providing a sewer vapor block. Click here for illustration.

2. Open both the black and gray water discharge valves.

3. When putting solids into the toilet, flush and then fill the toilet bowl twice (2 times) to the top with water and flush. The force of these (2) flushes will push all the solids out of the black water tank into the parks sewer line, stopping any vapors going up the tank vent.

UTILIZING YOUR RV TOILET TO MAINTAIN AN ODOR FREE BLACK WATER TANK
The correct way to hook-up your RV waste disposal system to the RV Parks sewer system has been stated above but to review.
1. Connect sewer hose to RV park sewer connection with a dip in the hose providing a sewer vapor block. Click here for illustration.
2. Open both the black and gray water discharge valves.
3. When putting solids into the toilet, flush and then fill the toilet bowl twice (2 times) to the top with water and flush. The force of these (2) flushes will push all the solids out of the black water tank into the parks sewer line, stopping any vapors going up the tank vent.

As mentioned above, the toilet must be filled completely twice with water and flushed.  Along with the weight and volume of water this action will push the solids and fumes out and down through the RV Parks sewer system. Depending on the make and model of your RV toilet, it may hold from 3 to 6 gallons of water when filled. This volume and weight along with the force of gravity is what cleans out your black water tank.
There are 3 primary ways you may use to fill your RV toilet bowl with water.
1. Fill a bucket from your sink and pour the water into the bowl. This process is cumbersome and takes time to do.
2. Depress the RV toilet flush pedal part way down until water enters the bowl and the toilet bottom opening has yet to open.  This process is slow and will prematurely wear out the spring system that operates the flush pedal.
3. Install a secondary water line nest to the toilet utilizing a simple kitchen sink spray hose. The spray hose will rapidly fill the bowl along with keeping the bowl clean. Installing this system is fairly simple and only takes a couple of hours.  We have outline the installation process below along with illustrations.

Frequently Asked Questions About RV Sewer and Waste Systems
Should I always use that expensive RV & Camping toilet tissue.
If you are connected to a RV Park sewer line you can use any brand that is comfortable to you. If you are holding your waste in the tank, such as traveling or dry camping, use the expensive stuff.

I've stayed at RV Parks that say don't connect with the tank valves open as they are on a limited septic system.
This is a common question and we answer it this way. What if you were checking into a motel/hotel and after paying the clerk said "please only flush twice a day as we have a limited septic system". Would you stay there?  If a RV Park is charging you for full service without providing an adequate  sewer system for its quest maybe its time to stay somewhere else.

What do I do if my black water tank is stopped up and will not drain.
The problem you have is the toilet tissue in the tank has surrounded and plugged up the tanks drain hole. Remember toilet tissue will sink to the bottom of the tank and is made from wood and when it dries out it gets very stiff. There are two ways to clear out the drain hole.
1. Use an item called "Termination Cap with Bayonet Hook and Hose Thread Connection". You should also have a Gate Valve installed just behind the Termination Cap. This item can be purchased below or at most RV parts stores or use the search box on the upper right of this page. You place this cap on the RV drain outlet and attach a hose to the hose threaded connection. After connecting open the black tank drain valve. Turning on the hose causes water to fill the drain tube and applies pressure to the underside of the black tank drain hole pushing upward into the tank. This should remove the stoppage. Close the tank valve and attach your sewer hose to drain the tank. Put a bucket under the outlet prior to removing the cap to capture any waste that is in the drain tube.


Do I need to put chemicals in my black water tank?

If you are traveling or dry camping with the tank valve closed, yes use one that will dissolve the solids and help with the odors. If you are correctly hooked up to a RV Park sewer system you will not need any chemicals.

I've hooked up my RV sewer system as per the instructions above and I'm still getting a sewer odor.
Check that your sewer hose is on a downward slope toward the RV Park sewer outlet and that you have placed a dip in the hose just before the Park's sewer outlet. There must always be liquid in this dip to prevent fumes from traveling up the sewer hose. If you are still getting fumes after this it is probably coming from your neighbors. You may want to instruct them on the correct hook-up procedure.

My wife uses tissue on every visit to the toilet. What should we do?
Unless the toilet visit involves solid waste we would suggest that the used tissue be disposed of in a separate receptacle. You will also only need to flush the toilet and not fill it twice as with solid waste. Men, always remember to put the seat down after use.

It appears that your sewer hook-up procedures waste a lot of water.
First off water is never wasted, it is used. Second the amount of additional fuel you use while pulling or driven your RV is wasted, never to return. Your toilet at home uses the same amount of water no matter if your flushing solid or liquid waste. Our hook-up procedure only uses additional water when solid waste are involved.

My RV Toilet needs to be replaced. Should I have it replaced at the shop or could I do it myself?
Since you own an RV you must be somewhat handy with tools and fixing things. So yes you can replace it yourself and it is not a difficult job. First off buy a replacement RV Toilet that is similar to the one you have. If you want to upgrade to a more fancy unit make sure its dimensions and water connections will fit in the same space as your current toilet. To replace the toilet do the following:
1. Turn off the RV water and disconnect the water line located behind the toilet.
2. The toilet is connected to the floor by two bolts. The bolts can be found by removing the plastic covers located on the base of the toilet. Remove both bolts.
3. Remove the thick rubber gasket from the hole beneath the toilet.
4. Insert the new rubber gasket that came with your toilet.
5. Position the new toilet over the rubber gasket and insert the 2 new connector bolts. Tighten the bolts according to the directions. Cover the bolts with the plastic covers provided with the new toilet.
6. Reconnect the water line to the back of the toilet.
7. Enjoy your new RV Toilet.
