I have never heard of this test. Do any of you guys have to do a “ball test” on your rough in? Here in St Louis we do a water test on the inside and pull a mandrel on exterior storm and sanitary plastic piping but the mandrel is only required for the public or the private under public inspection portion.

Not sure about here in MO, but in TX we had to do either an 8 ft water test on a rough or a 5lb vacuum test.

I prefer the vacuum.

At one time we could do a ball test if we couldn’t get the 1/8” per ft. They’d time the ball……

I've heard of the ball test having been done but it wasn't a requirement. Though apparently this one inspector would sometimes bring a ball of some sort, I think it was a large marble. It's not really a good test for a number of reasons.

Brachistochrone curve. Fastest route for a ball.

Now realizing that I totally misunderstood "ball test." Yeah, didn't watch the video, assumed it was a test ball.

Mee too.... I have never, ever seen that done before.... like why do you need to test
the fall on a pipe if you know how to use a common level???

using the rubber test balls and filling up the line looking for leaks
in the cast pipe was an absolute pain in the ass and
normally killed a day dealing with it....

The main idea behind rolling a ball through is that the pipes could have been good when you laid them but improper fill/compaction/concrete pour could change the pitch. A ball theoretically would get caught in a dip or a misaligned/broken joint.

I get that
but how are you gonna find the exact spot where the dip is if the ball gets stuck there??
That sounds like a great time over a slight dip in the line

You got it! Now you have a problem section AND it has a ball stuck in it. I guess if the ball is buoyant you'd be okay if it's not really broke. I think as was mentioned you time it and if it takes longer than you think it should you know there's a problem SOMEWHERE, but where? No one knows.

Maybe one of those sonde balls that Ridgid makes for flushing down a commode?

Might as well pour some water in and then run the camera looking for standing water.

Now I've seen everything!

I always saved the balls from ball checks for my kids to play with.

The title sure is misleading, I thought how much money you were making and or spending!

 

[Pipe Rat]

I think I'm going to order the Beech Balls or maybe the Cherry.

I love that "unknown" is an option for wood species. Mystery balls lol!

Being near the water there are some older neighborhoods with sewers that are laid flat. There where several ways they tested these and the ball roll was one of them. Also dropping a fishing cork into a cleanout while the sewer is flowing and timing how long it takes the cork to reach the lateral.

I was a kid when this was going on, probably12-13 so I don’t remember the details.
These were sewer replacements , removing orangeburg pipe and some clay. Cement pipe would also pop up. Everything……

It's like my Master says, a level pipe still drains.

Poohsticks is a game first mentioned in The House at Pooh Corner, a Winnie-the-Pooh book by A. A. Milne. It is a simple game which may be played on any bridge over running water; each player drops a stick on the upstream side of a bridge and the one whose stick first appears on the downstream side is the winner. The annual World Poohsticks Championships have been held at Day's Lock on the River Thames in the UK since 1984.[1]

I've actually played this game on the bridge by A A Milne's house.
