Has anyone ever used a 4 " stabber for an under water seat placement? I have always used a 5 " but it is only 40 yds at a 6" slump?

Thanks

I dont know the term "stabber" but We use only 4" steel or rubber on our underwater-pumping.... So I dont think it would be some kind of trouble , We have pumped docksides , windmills , lighthouse at sea and no trouble .

i have used 4 and 5 inch with no problem. but i always pour underwater at a 8 inch slump or higher so it will flow and spread

Try an anti-washout admix. http://goo.gl/SKMp Also, slump it up with super-P rather than water.

Whats a stabber?

thinking wall pipe??
