On pavement, that’s just a cleanup job — but on grass or soft ground, it can get your truck stuck. Worse, if you're drafting from a dump tank, that overflow is wasted water. The fix? Close the Tank Fill valve quickly and begin flowing water to the fire scene or fill site.

But there’s one often-overlooked step that can turn a solid setup into a soggy mess — and that’s what happens if you leave your Tank Fill valve open too long. ## The Problem: Overflow Can Sink Your Rig — Literally If the pump operator starts burp drafting with a full tank and leaves the Tank Fill valve wide open, that water’s got to go somewhere. On pavement, it’ll just overflow out of the tank — annoying, but manageable. But on grass, gravel, or any off-road terrain, it’s a different story. Too much water runoff around the rig can soften the ground and put your apparatus at risk of getting stuck. And if you’re drafting out of a dump tank, that overflow is straight-up wasted water — water that’s supposed to go toward suppression or filling another unit. ## The Fix: Shut the Valve, Start the Flow As soon as the intake valve is fully open and you're ready to transition to flowing, the operator should rapidly close the Tank Fill valve. That shifts the water flow from recirculation mode to fireground supply, sending water where it’s needed — not onto the ground. ## Tactical Reminder for Burp Drafting - Don’t ignore overflow just because it’s “just water.” - Always assess your operating surface. Pavement and grass are not the same. - Once burped, close that Tank Fill and flow to the fire or fill site immediately. This small but crucial move keeps your drafting operation clean, your truck mobile, and your water doing the job it was hauled in to do.   [![Download the Burp Draft Checklist](https://no-cache.hubspot.com/cta/default/46942026/interactive-192407794307.png)](https://blog.tft.com/hs/cta/wi/redirect?encryptedPayload=AVxigLKh31CFKewDarQAeTkrIh%2FqVOhDtAS5N2Q1OfIHCpByphGC2RZSsaan0ktpvFvk6uAFNWyHs9XUN9%2B0P4z0OPCr0L2apzJw4RNWlpraFPffQxn%2BtcvWl0TLZCJH5znfhSoPst2yYA13zs6rfbevM7UhON6%2BX2s2%2B7oBI4%2BvYHEmjjVMeGmt%2Bck%3D&webInteractiveContentId=192407794307&portalId=46942026) ### Share: [Share on Facebook](http://www.facebook.com/share.php?u=https://blog.tft.com/posts/why-closing-the-tank-fill-valve-fast-matters-in-burp-drafting&utm_medium=social&utm_source=facebook) [Share on LinkedIn](http://www.linkedin.com/shareArticle?mini=true&url=https://blog.tft.com/posts/why-closing-the-tank-fill-valve-fast-matters-in-burp-drafting&utm_medium=social&utm_source=linkedin) [Share on X](https://twitter.com/intent/tweet?original_referer=https://blog.tft.com/posts/why-closing-the-tank-fill-valve-fast-matters-in-burp-drafting&utm_medium=social&utm_source=twitter&url=https://blog.tft.com/posts/why-closing-the-tank-fill-valve-fast-matters-in-burp-drafting&utm_medium=social&utm_source=twitter&source=tweetbutton&text=Why%20Closing%20the%20Tank%20Fill%20Valve%20Fast%20Matters%20in%20Burp%20Drafting) [Rural Water Supply](https://blog.tft.com/posts/tag/rural-water-supply) ## Task Force Tips [Follow me on my website](https://tft.com/) [Follow me on Facebook](https://www.facebook.com/TaskForceTips/) [Follow me on LinkedIn](https://www.linkedin.com/company/1414962) ## Comments ## Related posts Search [How to Stop Hose Kinks at the Front Door](https://blog.tft.com/posts/how-to-stop-hose-kinks-at-the-front-door) [Which Foam Nozzle Should You Use?
