4 Fixes for Hard-to-Open RV Black Tank Valve
No matter what type of RVer you are, if you’re about to open your stuck black tank valve for the first time and fail, various questions can arise in your mind. Such as what kind of tools or labor is required to fix this issue, whether is it an easy fix or you may need to hire a professional, etc. You’ll get all the answers when you know the fixes. Even though the most traditional fix is lubricating, sometimes it can be more. Here are all the relevant fixes one by one –
Fix 1: Apply Vegetable Oil
You can start by lubricating the valve using vegetable oil. It’s a common household item and has more than enough lubricity, meaning it can reduce friction between two surfaces. Apply the oil on the handle and inside the gate valve box and make the valve open and closed. In some cases, the fix proves itself useful.
Fix 2: Apply WD40 Spray
The fact is that even though vegetable oils can be used as a lubricant, it isn’t as good as silicone-based lubricants. Silicone-based lubricants offer better heat and oxidation resistance compared to vegetable oil. The WD40 spray is a well-known silicone lubricant. So, apply it to make the opening process convenient.
Fix 3: Apply Dish Soap
Inner residues are one of the main reasons that make the tank valve hard to open. In this case, it requires to break down or loosen the residues from inside the tank. Therefore, a dish soap and water solution can be pretty useful. So, flush a powerful dish soap and water in the black tank. Then drive your RV around in a way that it makes enough sloshing of the mixture that gets down into the valve and breaks down the residue blockage there.
Fix 4: Make Use of a Hammer
There’s another fix to make the valve smooth, which is tapping on the valve with a hammer. Typically, this fix isn’t recommended and it requires expertise to apply. Yes, you can loosen the valve suitably by tapping it using a hammer, but you’ve to do this gently. Otherwise, this can even lead to a broken valve, making you spend extra money on replacing it.
That’s all about making the black tank gate valve easy enough to open. No matter what makes the valve so tight, the aforementioned fixes can make it appropriately loose.
