The Installation Process Of A Cable Operated Rv Dump Valve

Anytime you notice some liquid leaking from the waste dump pipe, usually, something is amiss. That can be corrected by either repairing the dump valves or, even better, replacing the valves.

In most cases, that will tempt you to hire a professional. But just a moment, do you know that you can get it all by yourself? 

Absolutely yes, if only you got the necessary guidance. But what is this article for if not to help you get the cable operated dump valve installed! No more stories. Let’s get it done.

Requirements 

  • Crescent wrench
  • Screwdriver
  • Disposable gloves
  • Goggles or any other eye protector
  • Work light
  • Petroleum jelly

Step 1: Get all the requirements

It is advisable to have all the nearby requirements before starting the actual work of installing the valves. That is to help save time and have an uninterrupted working session. 

Step 2: set the working area

The RV waste dump is at the bottom part of the vehicle. Consequently, you will have to lie down to access the valves fully.

Take a ground cover and place it underneath the waste dump valve. 

Step 3: remove the tank and undercarriage insulation.

In some RV models, the tank and the undercarriage have insulation. 

If your vehicle has insulation, carefully remove them.

 Step 4: unscrew the waste dump

When the insulations are out of the way, you can now see the waste dump valve handle extending from the rod. 

Using the screwdriver, unscrew the cable operated dump valve from the valve extension.

Step 5: Remove the bolts

After unscrewing the valves, you should see at least four bolts used to hold the valves in position. Please remove them and place them in a safe and conducive place.

In case the flange seals did not come out with valves, you can also remove them.

Step 6: clean the pipes

The leading cause of leakage in RV pipes is the debris in between the two pipes.

Thoroughly clean all the debris and spray with a silicone lubricant to simplify the assembly insertion process.

Step 7: Set the new flange seals for installation

Get your valve assembly package and open its gate to get the new flange seals.

Next?

Remove the flange seals and apply the petroleum jelly for lubrication purposes.

Note; any petroleum jelly can be used. However, you should ensure that it is applied generously. 

You are almost done! Get the well-lubricated seals and replace them on the pipes.

Step 8: install the cable operated waste dump valve

Now it is time to install the valves.

Get the new gate valve body, and install it in-between the two waste pipes as it was before you removed them.

Ensure that you keep the seals snuggly and check that they do not fold or dislodge.

Step 9: Replace the valves

Did you keep your bolts safe as I instructed? Perfect! Get them so that you can replace them.

Return the four bolts into their position in the assembly. 

First, insert each of the bolts loosely and leave them until you insert the four of them.

Then, start tightening each of the bolts without tempering with the seals. 

Caution; while installing the bolts, you should ensure that the seals do not move from their place. 

Step 10: Test

You need to test the valves before beating the road with your RV. How do you do that?

Fill the water tanks with the water and check if the new valves are leaking. If you have done the installation process well, there should be minimal leakages.   

How To Identify The Leaking Valve?

Before installing the cable operated valve, you should be aware of the valve to be explicitly replaced.

Nonetheless, distinguishing the leaking valve is not a comfortable ride. But never mind, I will help you get it right. 

  • To begin, you need to remove all the debris first from the system. To do that, fill all the tanks with clean water and flush them thoroughly to get rid of all the solid materials. 

  • After ensuring the tanks are free from all the solid materials, you can disconnect the waste dump hose

  • Lastly, close the valves and add water into one tank at a time. Wait for at least 30 minutes and check the results

The point?

Typically, you should see just a few drops of water. However, if the leaked water amount exceeds the amount of a standard cup, then that is the tank with the leaking waste dump valve. 

Conclusion

Now that you know how to clean moldy dishes, you can always take care of any mold problem in your kitchen. Precautions are a must as the fungus can affect your health. Never handle the molds with bare hands and stock enough protective gear.
