Testimonials

I live in my RV and have been using your electric waste valves for four years.  I hope to never be without them again!  Drain Master Electric Valves have changed my life.  After proper installation, my RV has never leaked.  Dumping black water is now as easy as flipping a switch from the comfort and warmth of the inside of my rig.  I would highly recommend Drain Master Electric Valves to any serious RV’ er who would like to expand their enjoyment of camping.”

Happy Camping!

We have a Prowler 5th wheel. Draining the black water was a real problem, I had to crawl under the trailer to pull the drain control. Now, it’s a breeze, just push the switch and the black tank is drained. I fill the tank with a hose and drain until I see clear water flowing. We love the Drain Master.

I would not live without a Drain Master since on my last RV, it was a wonderful thing. I live in a travel trailer now too and have one, and it is just the best invention. I tell everyone about it…..

We are really happy with our Drain Master valves. They make dumping much easier.

I have an Eagle and it takes 3 valves. They work really, really well. I am so pleased.

The Drain Master is a great mod to our 97′ Sea Breeze. It’s really convenient to just activate the switch and dump. I’ve coupled it with one of those piccolo pipe units that spray water in the tank while we dump. A couple of activations and we run clean and are finished! As I told National RV, the Drain Master would be a great addition to their RV’s.

Sincerely,

Warren Y.


I’ve got 2 of them – wouldn’t have anything else.

This is an unsolicited testimonial letter, to thank you for the outstanding service you provided on our RV during our visit to your plant last week.

We were having trouble with the electric dump valve on the black waste tank of our 2005 Phoenix Cruiser.  The key Phoenix executives felt our problem would be best diagnosed and solved by you and your staff – if we were “up” for the 150-mile round trip to Hollister and return to our home on the San Francisco Peninsula.

The purpose of this letter is to tell you-and any interested party-that the trip was well worthwhile.  You not only took care of the mechanical problem, you also provided snacks to tide us over until we could find a spot for lunch.

We arrived at your plant just before noon.  In no more than 10 minutes you and one of your factory mechanics were –literally- on the ground, analyzing our problem.  The two of you worked straight through the lunch hour, until you had replaced both the black and gray valves with your improved version of that part.  It was an important replacement for us because of the improved design of you manual over-ride feature.

You not only replaced both valves which you had manufactured-you also reinstalled a section of the waste line itself, because you noticed it was improperly aligned.

Needless to say, we very much appreciate the way you stand behind your product, and want to thank you for the courtesy and efficiency demonstrated during our visit.  We took off on a 5-day trip to the gold country the very next day and everything worked perfectly.

Thanks again.

Sincerely yours,

This Drain Master is fabulous! No more leaning down to pull a handle that is hard to move and sometimes breaks in the half open position, making the black waste tank useless. No more repairs on the handle and no more messy hookups.

Since putting Drain Master in stock, we’ve experienced great response. We chose Drain Master over other brands because we felt that their design was far superior to the other brands. Also, the service we’ve received has been outstanding!!”

Drain Master will enable me to operate the holding tanks so easily, without bending, kneeling and strain. A bad back and knees made opening and closing the valve very difficult. My toughest job is now my easiest.

Thank you for the great product.

P.S. Your new sewer hose is the best ever!”

FAQ's

[accordion][spoiler title=”Can I install Drain Master on my particular RV” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]Drain Master will fit easily on most RV’s. It takes up only a little more space than a manual valve due to the motor. Manual valve dimensions: W 9 5/8″ x H 4 1/2″ x D 3/4″. Drain Master dimensions: W 10″ x H 6″ x D 1 3/4″. You will need additional space if you are installing on 1 1/2″ piping as you will need the separate reducer kit.[/spoiler][spoiler title=”Can the switch be placed outside the RV” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]The operator switch (Pt 5528) is weatherproof, but it is not water-proof, therefore, it should not be installed on an exterior wall. Placing the switch in a compartment protects it from the elements as well as grandchildren’s swift and nimble hands (yes, OMG).[/spoiler][spoiler title=”How do I know my Drain Master is installed correctly” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]As long is the valve is installed with the motor in an upright vertical position, you will install it correctly. We also have excellent Drain Master installation instructions that will walk you through the installation step-by-step. You can also call us toll free 877-787-8833 with any questions you may have during installation.[/spoiler][spoiler title=”I’m getting ready to install my valve and notice that there are gaps of space when the gate is closed. Won’t this cause it to leak?” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]The gap at the bottom and top of the gate is part of the design. The sealing against the gate takes place on the gate surface where the round lip seals are on the gate when it is closed. The gap at the top and bottom were necessary to achieve the interchangeability of existing industry standard 3” manual gate valves, which also have a gap top and bottom. The graphite impregnated rubber seals on both sides of the gate make the valve bi-directional giving it more installation options.[/spoiler][spoiler title=”How do I know if the valve is open or closed?” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]Simply push the valve switch to the close position to ensure the valve is closed. If you purchase the LED operator switch, the red indicator light will tell you anytime the valve is open. The RED light will go out when the valve is completely closed.[/spoiler][spoiler title=”How does Drain Master differ from the other Electric waste valves?” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]Drain Master is an electric waste valve; the others are attachments to a manual valve and take a long time to open and close.[/spoiler][spoiler title=”How long will it take me to install Drain Master? Can I do it myself?” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]The average time to do an installation is about 1 hour.

Note that failure rarely occurs with these valves and here’s why. Heat is the major cause in all motors. Drain Master valves are so fast, there is simply no time for the motor to heat up, thus, it will always be at the outside ambient temperature. If you DO have to replace the sealed unit, you can order the Premium Replacement Valve kit.[/spoiler][spoiler title=”What size is the valve?” open=”no” style=”default” icon=”plus” anchor=”” anchor_in_url=”no” class=””]The Drain Master valve is a 3 inch valve.
