I am running 3" system on my trailer pump. Which would take less pressure to make a 90' turn. A wide sweep steel 90' elbow or a 10' pc of rubber at a bigger radius 90'. Assuming space is not an issue.Terry

steel always less resistance,as I recall 40' of pipe = 10' rubber hose

go with sweeping 90  steel every time your hoses will jump less

Are you still pumping.

Ya trailer pump seems to run in streaks. Belt has been going out just about everyday.Need a twentyfive year old kid to run the trailer pump though.

Yeah because the under 25 crowd is stupid enough to say yes to a job like that.  Trust me I did, and I kick myself everyday for it.  I love it, but it sucks at the same time.  Better than being a laborer though.  

Oh and steel, I was taught to never run hose before pipe.  The one time I tried it because thats all I had to make it work, she clogged really bad.  We tried this in the middle of a pour to not have to move around the building to get this one little spot.  We ended up moving anyway and just wasting time trying that.  That was blended mix though.  Grout and pump mix it works fine for in 3" line.  

I always run a 10' hose off of the reducer to get to the pipe on the ground,never really had a problem with it. I usually lay out pipe frm the pour then back to the pump. The 10' hose is the transition to the reducer on the pump. Experimented with a few different priming techniquies and think I has settled with useing plain old portland. 2 buckets on just about every job and never a problem. Maybe go back to trying betonite when I get a little extra time to experiment.

Terry i only use rubber but my mix must be more pumpable. 3" system is tough i don't use it. Man i can only imagine, 2.5" is heavy enough. I've been using the heck out of my line pump lately.

For sure everything is heavier than crap with 3" The 10' steel pipe is a lot easier to handle than25' pcs. of rubber full of concrete. If I am dumping them as I pump just unhook flip them up on end to dump them and wash them out with the redimix truck. 3" 25' rubber hose are a pain in the azz. Did 300' push yesterday all pipe except a 90' elbow on the end and a 25' hose. Hardly made the needle move! Sure helps having a helper if there is enough money in the job. He was cleaning pipe and clamps as the pour progessed so when we were done just clean the pump and go.

Try some 2.5" you will never touch your 3" again. I haven't used mine in ? 3-4 years. If your pushing 300' successfully it will work with 2.5' Also wash out is a breeze with 2.5" just stuff a foam tennis practice ball in the reducer fill your hopper once with water and pump through. 3" takes too much water.

3" system all came with the pump. Not in the budget to switch over to 2 1/2" at this time. Is all of your 3" stuff hose? I am maybe looking for some more 3" pipe. Maybe a road trip to MN. this winter.

No pipe,never used it. Yeah 2.5" is about $450 per 25 footer i had to replace one last month i got it from CPR in MN. I carry 6. Cheaper than a chiropractor however.

I was hearing that a lot of guys were using 2.5 inch hose for eveyrthing.  I have 2" on my truck.  11 25' sections on the truck.  Plus I have  2 more 25' sections and 1 50' section at the shop.  As soon as our JAX job is done I will have all my 3"(400') and more 2" (6 50') to lug around.  I also have a 50' 1.5" whip I hate using.  That only comes out for our one mason who perfers it, if we can get it to work.  I have a huge arselal of system for just our little company.  Boss was going to buy another 100' of 3" pipe, but the order never went though our pump guy, its been 3 months since we ordered it.  He always wants to be prepaired for anything and everything, even though he knows what we have going 6 months in adavance or more.  

If you think 3" is heavy I have a trailer pump guy not to far from me that only has 4" system. Get a few customers from him because my 3" is easier to drag around.

Ha yeah for sure. I guess three inch you get used to. I keep mine on my pump truck just in case i can't reach the job.

The boom operators in the south and east get a daily work out on 4"/5" and still live on.You line folks should price it to include a laborer,just sayin.

we mainly use 4 and 5 inch system here where i live. Every once in a while we will use 3 inch system off the end of our 4 inch system to make it easier for Hose A and Hose B (Guys running the hose)

heres a few examples of normal trailer pumpin
