Bottom of Overfill Flapper Valve fell into tank

Post by MarkWallace » Wed May 16, 2018 11:56 am

My Tech was removing an overfill flapper valve/drop tube from a tank (for the "new inspection/testing regulations") fill pipe. The top 1/2 of the flapper valve came out, but the bottom 1/2 fell into the tank. Any concerns with leaving the drop tube laying on the bottom of the tank?

Anyone else had this happen to them?

I don't think I would lose sleep over it. If you don't have a manway you don't have much of a choice.

Although, it could mess with the floats on the tank gauge. Odds are it won't, but Murphy has a way.

Just curious - when the suction fitting is at the top of the tank, is there a stand tube from the fitting down to the bottom of the tank?

A stinger runs from the top to the bottom of the tank. Older suction site stingers may have a "foot" check valve as well. What one sees on top of the tank looks kind of like an ball check extraction fitting. The 2" stinger NPT attaches to a NPT 2.5 or 3-inch extraction bell reducer or bushing and a cross bar extraction tool is typically required. Most are rotted off however and it becomes difficult to remove or replace. Finding the tank top fitting can be difficult as well as most access points have been paved or concreted over.

Had a Call out from a delivery driver that an over fill looked a little weird, when I arrived on site the bottom half was just hanging on by one screw. Undoing the fill collar was enough for the bottom half to fall into the tank. This was 4 years ago and still have had no issues arise . This tank was equipped with a TLM and STPs as well.
