Black Tank Flush

[benagi]

Anyone had problems with getting their black tank flush to work properly. I know you are suppose to open the black tank drain, then start the flush but water squirts back at us at the connection. Anything else we are missing? Thx, Ben

Benagi - we haven't had any problems. Just as you have stated you hook up the hose and turn it on! I usually rinse with the valve open for a while and then a few times with the valve closed. I only run the washer with the valve closed for a minute, just so I get a good flow exiting the valves.
Good luck.

Mine does not leak at all. Can you hear water flowing? If not pull off the screen and seal to see if anything is blocking. In my last TT I had an issue that the black flush hose to the black tank was kinked. I can't say for sure but you may be able to check it from the bathroom hamper or sink.

A side from one time when I did not get the hose threaded in tight and it sprayed me good I have not had a problem.

I would try adding a second hose washer to see what happens.

I would guess its a check valve issue. It could be bad. Or it could be low water pressure. The check valve could not open under too little pressure.

Mine works just fine. But I had a stuck check valve on my TT flush and it acted as you described.

I couldn't get any water out of my outside water sprayer/shower, come to find out the check valve behind it was installed backwards. Check you spray wash line check valve perhaps yours is in backwards not allowing water in also forthe leak have you checked to be sure there is a gasket at the hose fitting?.

Went camping today for more testing. We got a full hookup campsite and were able to test the black tank flush. Tighten the water hose real tight this time and put full pressure to it. Worked like a champ. Thx for the above replies.

The way the check valve works if it doesn't see adequate water pressure it will not let water pass through as it should.

yes I had problems with water spraying back at the black tank flush connection. I was using an old garden hose that had an old stamped brass male connection on it. the threads were pretty shallow. the female connection on the trailer is made of plastic and the threads are pretty sharp. the two just leaked when connected. I go one of those collapsible fabric hoses with plastic connectors and now the two connect without any leak! plus the collapsible hose is lots easier to store.

Just a word of caution....

When attaching 'any hoses' to the outside (usually plastic) connectors it is always wise to relieve some of the down force of the weight of the hose leading to it.
I do this by using different adaptors ....Like these:

They really help should anyone trip over the hose and reduce the angle and the force put on the connector threads,

Hope this helps
