Dual flush valve installs on your RV's holding tank drain so you can rinse your holding tanks and sewer hose with an ordinary garden hose. Anti-siphon valve connects to your faucet to keep your water source free from contaminants.
The dual flush pro is a great concept for ensuring your black tank is clean. The one issue I have is the flimsy design of the flush hose connector. It causes a lot of the water to leak out. But with a little manipulation it works fine.
This works very well. I have used it now for a year. Helps keep draining the tanks sanitary. Also good for a tank wash and also cleaning the tank pipes occasionally. Very durable. I leave it on when I travel.
I have purchased many items from etrailer and I am a customer for life. They are the best even when shipping large items. When I need something for my trailer I always look at their web store first.
What a great company! From the very user friendly website and their helpful videos to their customer service department. I shopped around a lot on other sites, and by far and above this was the go-to place for trailer related items. It was nice that they had my items shipped within hours of me placing my order and their follow up emails were very helpful.
this works really well on my travel trailer. for the price it does everything it is supposed to do. Very good investment
Tried it already and it works exactly like it should and is well made. I looked at the other ones and found this one without the bend in it that leads into the sewer hose. This is what I need since my trailer sits pretty low thus the holding tank plumbing sits low. Great product and well made.
Awesome product, great design. No more dealing with disgusting, smelly leakage after removing the cap to hook up the sewer hose.
Items ordered arrived on time and in perfect condition. Can't use any of them till the snow melts. All I can say is that etrailer service is fantastic.
Still works great a year later!
Outstanding. This was exactly what I was looking for and and it worked as intended.
Unit operates as per advertised, I have real bad problem and did not clear it, but unit work very good
It was a great site. The product I ordered arrive very quickly. I installed it yesterday and it works like a charm. I can't say how much I appreciate the help I received choosing the right product for what I needed.
Thank you and I will certainly keep this site for my future needs for my Montana.
