The decision to switch from manual to electric RV dump valves is a personal one and depends on what you choose. You may choose the convenience of hassle-free dumping or the comfort of almost no-repair requiring manual dumping valves. We have carefully prepared a buying guide for electric dump valves to help save you from the hassle of continuous repair and maintenance of malfunctioning valves.
- The Quality of Materials:
The materials used in the construction of valves determine their durability. Most of the electric dumping valves are manufactured from steel, aluminum, and plastic with some rubber as well. As the valves are frequently in contact with the water and waste materials, they must be made of high-quality materials that will not corrode, rust, disintegrate or deteriorate with constant exposure to moisture, soap, and other waste materials.
- Price:
Some people will consider the electric dump valves just a waste of money. But if you spend most of the time on your RV, they are worth it. Once you become addicted to the convenience they bring, you will not mind the money spend on the electric valve.
You may find cheap options available in the market, but they may be made of inferior quality materials. Installing electric dump valves is a hassle, and you may not want to replace them often. Above all, malfunctioning electric dump valves can ruin your RV picnic. You will not want to be fixing your RV dump valves at the campsite or a mountain adventure. Therefore it is better to spend a few more dollars to grab more reliable electric dump valves.
- Brand:
The name of the manufacturer matters a lot when you are going to buy such a sensitive device. Low-quality valves made from substandard material will just become a day to day hassle. Selecting the electric dump valves manufactured by reliable names is a better decision. It may also give you a good warranty for repair and replacement. It may cost you a little bit more, but a reliable and good quality product always pays for its price.
- Number of Switches:
At how many points in your RV you want to mount the switches? Most of the dump valves only come with one switch and buy a separate set of switches if you're going to mount them at two places. Still, some valves support only one switch. So the manufacturers do not advise putting on additional switches for them. Check this detail from the product description before you buy a dump valve.
- Installation:
How much technical skill do you have? Can you install an RV electric dump valves by yourself? The answer to this depends on your electrical and plumbing knowledge. Most of the RV enthusiasts prefer installing their RV dump valves by themselves. In this case, you must follow the manufacturer's instructions and do the installation on empty and clean tanks. You may also take the help of RV technicians or bring your RV to an RV service station.
- Maintenance:
Consider the amount of maintenance required in order to keep the valves in good functioning condition. Some valves can be used for months without requiring maintenance and care. They just require proper lubrication periodically. You can get to know about this when you check customer reviews.
Some valves can be lubricated while they are in place, while some need to be taken out from the flanges to get the required maintenance. It may increase your maintenance cost.Installing Drain Master Electric RV Waste Tank Valves
Installing the electric dump valve yourself or taking help from RV technicians is a personal decision. Before installing a drain master electric RV waste tank valve, you must have some basic mechanical and electrical knowledge.
If you prefer doing small mechanical and electrical tasks by yourself, you can conveniently install the electric dump valve. Follow the instructions given on the user manual or on your manufacturer’s website to make sure everything is done right.
Things You Will Require:
- 7/16” wrench/socket.
- A 12 V DC Power source where you can connect the switch.
- An electric dump valve kit. The package usually includes valves, seals, operator switch, bolts, nuts, DOW 111 lubricants, and manufacturer's instructions.
- The premium systems do not require a fuse for the switch.
- The standard systems require glass type 5 Amp Fast Blowing Fuse ( Automotive Blade type fuses are not adaptable)
Instructions for Installing the Valves:
- Preparing the Tanks:
Before you remove your old valves, it is vital to clean your tanks thoroughly. Cleanest tanks are better when you are working under your rig while the pipes are open.
You may increase your waste treatments and go for a few black tank flushing a few days before you intend to install your dump valves. You can use the manual flushing wand along with the built-in flush system for extended flushing.
- Removing the Valves:
For removing the old valves, slide them out by unscrewing its four bolts. It is better to install the rubber sleeve on the grey tank than install it on the black, as there is a possibility of leakage.
- Installing the Electric Dump Valves:
Before installing the dump valves, check out every little detail too regarding the valves and associated drainage system hardware. The pictures and diagrams are readily available online. You can also contact the company’s service staff for detailed guidance.
Clean and check the RV's sewer piping and its flanges for any cracks or chips. Now attach the gaskets which are provided with the valve to the flange. Do not connect it to the electric valve during installation.
Now apply the given Compound 111 to the valve blade and rub on both sides. It acts as a valve blade lubricant. Now slide the valve into the flanges and gradually work out the pieces together. Do this with a slight twisting to accommodate the gaskets.
Lastly, add all the four bolts and nuts and tighten those together using a cross pattern. Its suggested torque is 20 inches/lbs. Over stiff nuts and bolts can crack the plastic.
When you install the valves, the motor should be facing up to a plane level. The recommended position is perpendicular up and down with a little bit of flexibility.
- Installing the Wiring:
Once you mount the valves physically, make sure that there is no leakage. Now you can connect the electronic control switches and wiring to the 12 V DC power source.
Select the place where you want to install your switches—cut out a hole and place the switch plate with the given screws' help.
Connect the electric valve with the electronic switches with the help of data cables. Label the respective valves or black and gray. You can plug-in the data cables without the use of any tools. An extra plug is given on each valve in case you prefer an extra set of switches in your RV.
You can power it from a battery compartment or the main power distribution panel. You can use a 5 Amp separate fuse for both valves or a 10 Amp fuse if they share the power.

- Electric Dump Valves Prevent Tank Leakages:
How do you lubricate an RV dump valve?
The 3” valve on the black holding tank and the 1.5” gray valve become sticky with time, especially when your RV is not in use. Drying of the tank components causes a sticky layer to form on the valves.
- Cleaning:
Before you lubricate the valves, it is essential to empty and clean the tanks. Fill the tank with clean water and dump it. Repeat the process until the sewer ground inlet becomes clear, and no sediments are visible.
Separate the valves from flanges that join them with the piping. Now mix some detergent in hot water and soak the valves in it. Shake the open side of the valve in the water. It will remove the waste particles that accumulate inside the valve with constant use.
When the valve's inner body seems to be free from debris, remove from water and blow in air to remove the remaining particles from inside.
- Lubrication:
Now apply Dow 111 synthetic grease to the valve. Apply a thin coating of the lubricant to both sides after closing the gate.
Separate the seals and flanges and check them carefully for any cracks or damage. Replace if required. Then put a thin coating of grease on the seals and put them back on the flanges. Without moving the seals, put the valve back inside the flanges.
Hold the flanges tightly together to insert the bolts and nuts to secure them. The flanges should be tightly pressed against the valve while you place the bolts and nuts.Fasten the four bolts and nuts with the help of a wrench until it is tightened up to 20 inches/pounds torque. Over tightening may cause harm to the flanges and valve.
How to Lubricate the Valve without Removing It from the Flanges?
If you want to lubricate the dump valves without removing them from the flanges, you will need to install a grease zert, often called access port. It allows you to lubricate the valves by removing them. It makes the valve lubrication convenient and hassle-free.
Put a hole in the broadest part of the valve at the top from where the SS shaft is removed when pulled out from the body. This thickness makes it possible for you to tap on the body. Then you can enter a plug or grease zert.
This hole should be in the middle of either side of the SS shaft hole, nearly ½” distance to the SS shaft.
Applying excessive grease on the valve will make it difficult to pull and push. A plug is a better option as it allows you to use a silicone spray into the hole before plugging in.
Tip to Reduce Valve Stickiness:
While installation, keep the valves so that the valve body remains in the 3 – 9 o'clock position. In this way, if the water enters the valve body, it will go back to the pipe's bottom. When valves are not installed in a 3 – 9 o’clock position of the lower handle, the water remains inside the valve body and causes stickiness.Conclusion
The RV electric dump valves are the latest innovation in the RV lifestyle. They allow you to drain your RVs black and gray tank contents with the flip of a button. They provide the convenience of operating the RV interiors' valves, a much significant feature for harsh weather.
Select the best RV electric dump valve to avoid frequent repair, maintenance, and replacement.

FAQs
How do you keep RV dump valves from freezing?
Several ways can save the RV dump valves from freezing. You can add a safe electrical heating source to the RV pipes and dump valves. The heating source's temperature must be controlled carefully to prevent the valves and pipe contents from damage.
Adding “Non-toxic RV Antifreeze” to the gray and black tanks will prevent the contents of the tanks as well as the dump valves from freezing.
Should I leave my black tank open or closed?
If you leave your black tank open, you will drain all the liquid and the solids will remain standing there in the tank, causing contamination. You must completely close the dump valves on your black tank after you are done with dumping.
Does wd40 damage rubber seals?
Some people will say that WD40 can be safely used on rubber. However, it is better to use a silicone-based lubricant as the prolonged use of WD40 may cause damage to the rubber. WD40 is not ideal for use on rubber and may deteriorate it with time.
What is the best lubricant for rubber?
Silicone lubricants are the most recommended for use on rubber O-rings and seals. They are best for lubricating and water-proofing the rubber. In this way, they extend the life of the rubber and make it usable for years. Vaseline should not be used to lubricate rubber; it may cause damage to the rubber.
