I've got a few new customers that are doing more and more core filling with the boom pump and i was wondering if any one has any good  ideas or hose ideas for doing such. What i have been using is a 5-3 reducing hose but this tends to be messy especially with out a hose cuff. i would like to reduce down to 2.5" with out putting on many reducers. Maybe like a 5-2.5" reducing hose or a 5-3" double 90 on top of a 3" hose? Something safe and easy to put on and off.

use a rams horn

DO NOT us a rams horn or any other attachment. Use a pour end hose only. No metal ends.

Brain I might be wrong on since you are using a 5 TO 3 steel reducer then why not ad a 3 to 21/2 steel reducer,also I used 4000 grout on rock it fills better and like these guys are telling you I woundn't use any rubber hose at all, one other thing I can build you one of my easy turn wall hooks I will buid it for Free and shiped to you just to help.

Thanks Ed but i don't have a 5-3 reducer its a reducing hose all rubber and 10 feet long. The mud still comes out fast. If i reduce down to three inch it takes two 3' reducers and a hose its still cumbersome and fast. I was thinking maybe a 5-3 reducing elbow with a three inch 90 welded on with a 3" hose off the end but it might plug? or maybe a 5-3 inch short reducer with a three inch hose off the end. if such a thing?

12 in block not to bad with a 3 in end,but 8 in block you are going to make a mess,unless you got something  to put on top, I only used a line pump 2 1/2 in hose and a easyturn wall hook wasted very little, I'm sorry but some of you are hard headed and thats another reason you never got much out of Ray,and thats my story and I'm sticking to it.

We regularly do upto 130 cubic metres of core fill with a 5-4 then a 4-2 reducer either a 2 inch 4 metre whip or 20 metre hose. Helps to pump the hopper down after each load and pump in reverse full flow keep the s tube getting build up. 

Ed i was talking about using the boom pump. People do not want to drag hose if a boom is available.                               Here is what i was thinking but reducing 5-3" elbow then 3" 90.

Tip section  5 to 4 reducing 90 into 4 to 3 reducing 90 into a 3 to 2.5 straight then 2.5 placing hose ?

I have used a 5-3 reducing 90 with a 3-2 1/2" reducer with a 2 1/2" mudsnake.

Another option im considering is a 5-3 straight reducer with a 3 inch non ended tip hose. maybe with a throttle in the end of it or choke. No metal exposed of course..

Charge more bring your on hose draggers do everything from the inside less dragging I had to do it, home builders in Tenn are like a broker they don't have a crew of worker most jobs I never seen anybody, but always got paid. I guess you can keep on making a mess some contractors here use a spray sealer on the out side and inside the block has to be clean on sides and footer or they can get a water tite seal.

Eric is on the money.

I would think that if you could shorten the free fall from all the hose from the tip of the boom that would help.  Even a 2.5" hose droping 30  feet has a lot of force behind it.

I need a 5-4 metric reducing elbow. I have a 5-4 but it wont work. I should have saved my old 4" rams head and welded a ring on the bottom  mount it to the top of the hose.

doing line pump work with a boom is ridicoulus. the mess that the contractor has to clean up is good enough for them

Pumperman460  thats what a few  of us have been telling him,there's and old saying from Forest Gump

stupid is stupid does.

If you dum ass'es would rather hump hose be my guest. Thats why i own a 300k machine.

They must not use/put much steel in the walls if y'all are using boom pumps to do cell fill

Brian you never said you were pumping ICF's in your post some off us Southern Boy's  seldom see foam 99.8 persent here is 12 in and 8 inch cement block thats why I said what I did.

I charge the same rate for my telebelt as my trailer pump. I guess let the customer decide. Belts work well for ICF's jusr neck down the hose.

Yeah Ed i was moody Sorry, but actually i am working in to getting the cheap skate block laying contractors into pumping their floors and doing the core fill at the same time. I do a lot of pump the basement floor them the block fill same job. Up here there are no inspections so they fill a core every 4 feet wilth no bond beam.
