Where to Install RV Electric Waste Valve Interior Switches

Benefits of Interior Switches

Why would you want to install RV electric waste valve interior switches in the first place? Well, there are a few reasons why doing so can be beneficial:

You can dump your RV holding tanks whenever you need to. Normally, inclement weather such as heavy rain or snow would prevent you from doing so, but an interior switch allows you to empty your tanks when necessary. This is a Great Video from David Bott, Outside Our Bubble, showing how it works!

You can keep your gray water tank closed. This helps you avoid problems such as odors from the sewer system seeping into your RV and Rodents being attracted to your open tank.

Safety

The Recreation Vehicle Industry Association (RVIA) allows for just one situation in which interior switches are permitted: when they are tied to the ignition. This is for safety reasons, since it keeps the switch from operating while the engine is running.

Installation & Master Switch

Drain Master offers easy installation of valves and switches, especially when you pair our Pro Series valves with our Master Switch. The Master Switch safeguards against unsafe and accidental dumping by disabling switches on valves. This way, if your children start pressing buttons inside the RV, they won’t trigger any unwanted dumping of waste. The Master Switch is ordered separately from the Pro-Series Valves, which come in kits for one to four tanks.

So, where should you install your interior switches? Here are a few ideas.

We suggest one in the bathroom for convenience when showering – if the shower pan begins to fill, you can simply reach out and push a button to open the RV dump valve.  But one of our customers had a great idea.  Why open the shower door to reach the switch?

And customers with a washer/dryer in their RV will often install a gray water switch right by the washer so they can open it before running a load.  Very convenient.

We may be the RV waste specialists but we have to say, some of the best ideas come from our customers.

Drain Master Waste Valve Differences

We get asked a lot “What’s the difference in the Premium and Pro-Series valves?” The actual valve is the same physically so no additional installation steps are needed to interface with your existing plumbing. The difference for the Premium electric waste valve versus the Pro-Series is in the actual operational flexibility.

 

EASE OF INSTALLATION

The Pro Series valve is easier to connect the power 12vdc because it is done at the valve, not at the switch. The switch interfaces with the controller through a small easily run cable (RJ 11) much like a telephone land line wire and has both a Green light indicating Closed and a Red light when the valve is Open, so you always know the status of the valve. In addition the controller on the Pro Series has 2 ports so an additional switch can be added OR it can be connected to a computer. The future of RV Waste Management is to automate the dumping process and the Pro Series is ready to go.

As you can see in the pictures above our older Premium valve switch has one red light that lights up anytime the valve is open. However with the Pro-Series valves there are red and green lights and two different styles available. (pictured above)

 

WARRANTY

Another thing that sets them apart is the warranty.  The Premium Drain Master valves come with a 1 year limited warranty while the newer Pro-Series Drain Master valves come with a 5 year limited warranty.

winter branch with ice - winterizing holding tanks

You Might Be Missing a Step When Winterizing Your Holding Tanks

Most RV’ers know that it’s essential to empty and clean your grey and black holding tanks when storing your RV for the winter months. You’re probably also aware that you should put some RV Antifreeze in your holding tanks, since you can’t be sure that there isn’t some water left.  A question we are asked a lot is “Should I leave my valves open or closed when storing my RV?”  The valves should be left in the open position which allows the seals to be in a relaxed position over the winter as opposed to pressing on the gate, causing a potential for stiction.

But won’t the antifreeze just run right out of the tank if you leave the valves open?  Our suggestion is to run enough antifreeze through the toilet and into the holding tank to insure no water is left in a low spot in the holding tank. Then pour some in the toilet without flushing, so there is antifreeze in the bowl.

Adding a Second Switch Inside Your RV for Drain Master Electric Valve

Over time and talking to our customers it became evident that we needed to develop a simple system for our customers, without a lot of electrical background, to install a second switch in the living space of the RV. Folks are beginning to understand the importance of keeping the gray valve closed and only open when the tank is 2/3rds full. Putting a second switch inside for the electric RV dump valve makes it simple to empty the tank with a push of a button after washing clothes or taking a shower.

standardized flat plugs - electric rv dump valve

We standardized on the Mate N Lock style 4 pin flat plugs many years ago.

extension cable - rv dump valve

Every valve we sell for use in RVs has this plug on the valve, unless the RV mfg. specifically ordered valves  without them.  We then offer a number of extension cables that plug into the valve and go to the operator switch wire harness so it is a simple matter of plugging each one together.

Here is a diagram that illustrates how everything plugs together.

Fast Flow Pipe - learn about the best sewer hose around - Waste Master

Does Dumping the Black Tank 1st & the Gray Second, Clean the Hose?

Every RVer knows that dumping the Black water, then the Gray water is to insure any residual Black water will be flushed down with the Gray water—but is this really true? After we answer this age old question, stay tuned for information on the best sewer hose we’ve found that works wonders in keeping you and your RV clean.

Actually it is, providing your Gray water dump valve and drain piping is 3″. Unfortunately many RV manufacturers still use 1.5″ piping and valves on the Gray water tank outlets. What actually happens in this case, is that only a very small portion of the inside of the sewer hose is cleaned.  Probably looking a lot more like this

slow flow pipe - waste master best sewer hose system

But this theory of dumping the gray water second, assumes that the water flow goes a little more like this

fast flow pipe - waste master best sewer hose system

To get maximum hose flushing action, the Gray water exit valve and piping needs to be 3″.

Here are the reasons:

1. It takes 2.56 times longer to empty a 35 gallon tank through an 1.5″ hole than it does with

a 3″ hole.

2. With the overall flow slowed so much, the water doesnt rush down the hose as it should,

cleaning the whole interior of the hose.

3.  As your Gray tank fills, a scum forms on the top of the water, generated from soap, oils,

shampoo, toothpaste etc. When the valve is opened, the faster the water exits, the

more it creats a whirlpool sucking the scum out. This action is minimal to non existant

through a 1.5″ hole.

Converting your existing system from 1.5″ to 3″ on the Gray tanks can only be done if the Gray holsing tank has a 3″ collar with a 3″ to 1.5″ reducer in it. You will be able to tell by looking at it. The first sign is, there is a band clamp around the tank collar.

Second is some white looking paste around the fitting area where the reducer was inserted. This material doesnt ever harden fully, so you can loosen the band clamp and by moving the reducer back and forth with pulling pressure on it and a little patience the reducer will come out. If your tank has a 1.5″ tank collar you are better off aborting the project.

If and when you look for a new RV, make sure you look to see the plumbing system detail, it is the area you do not like to go near, so be sure to check this area out before you buy. The devil is in the details and most folks buy the bling first, then are stuck with the issues that they didn’t look for in the first place. Finding the best sewer hose for you is also important, so do some research on various systems before getting something you won’t be able to use or clean.

Ever Get Sewer Gas Smell Inside your RV? Time for a P-Trap

If you have ever experienced that unmistakable smell inside your RV, you absolutely know it is not supposed to be there EVER! Why it came into the living space of your coach is in all probability for one or two reasons. If you have been travelling down the road when you smell it or enter the coach when you stop, the possible problem is water has escaped out of one of the P-traps in your sink or shower, breaking the “water seal” created in the RV P-trap and allowing the sewer gases back into the living space of the RV.

water traps sewer gas - rv p-trap

The other possibility is that the holding tank roof vent allowed the outside air to enter the vent stack, creating a positive air pressure in the holding tank and the air is seeping into the living space through a poor seal somewhere.

diagram of rv with and without vent cap

With our most recent partnership with 360 Products Inc. we are in a position to help eliminate sewer odors in your RV once and for all, guaranteed. As you may already be aware, we sell the HepvO waterless RV P-trap which eliminates the issue of water spilling out of the traditional P-trap, however, if you have positive air pressure in the vent system, the potential for sewer gases to permeate the living space still exists.

We have looked in the past at carrying a roof vent but any of the units that worked required moving parts. The first on the market to address this problem was the 360 Shark Fin that turns in the breeze, causing a negative pressure in the vent stack and holding tanks. It’s popularity with consumers caught the eye of a couple of companies known in the RV Industry for “knocking off” good products and two more appeared on the market. The original inventor of the 360 Shark Fin knew this device had limitations, and his goal was to make a product with no moving parts that was very low profile and would never allow a negative pressure in the vent stack, under any wind condition. Five years in development and hundreds of models tested, the perfect unit emerged and they could not make it fail in any of the test labs it was sent to!

We are proud to be partnered with 360 Products Inc. and with the 360 Siphon added to our waste management product family, we feel all our products are designed to make your RVing experience uneventful when it comes to dealing with human waste issues.
