Priming the boom using just a little bit of water, and cleaning it out with a whole lot!!!

[@rafflegiveaways]

My favorite sound when doing a water wash is that loud ( cracking ) sound and the end of a good washout

[@canadianconcretepumper1979]

Not matter how many times I hear that, it still brings a certain feeling of accomplishment each and every time.

[@EM0601-x4h]

Buddy wanted to hold that hose during prime out so bad lol you get an air pocket or plug up someone would be picking him out of the trees somewhere

[@StephenKnowlesProperty]

I was thinking the same thing, please don’t hold that, don’t hold that yet, stand back please.. how many times do you tell people 🤦🏻‍♂️

[@canadianconcretepumper1979]

Lol! It’s almost as if there’s a magnetic force which draws concrete placers to the end-hose 😂😂😂

[@tat1ukpable]

Haha I reckon this happens all over the world, I certainly say keep out of the way of it! You get a ok still holding it

[@yotaforlife8408]

I use a slick pack and just fill up to the bottom of the barrel and just send it ahead of the mix at a good speed like a 8 and slow it down when i hear it hit the last section so it doesn't cause any kick back on the hose when its falling through the reducer

[@canadianconcretepumper1979]

I’ve been using the “Kick Start” product from Concrete Pump Supply lately. It functions very similar to slick-pack except for that it comes in liquid form and seems to gel up quite a bit faster. Just dump an ounce or two in the hopper and add a few gallons of water. I’m a big fan of using primer (especially on the bigger booms), it just cheap insurance IMO 👍🏼👍🏼👍🏼

[@Andrew-Ponce]

Love the content. Makes me want to get into the big boys pumps. For now I need more content with that TK60. Or maybe how you use that backset acid.

[@canadianconcretepumper1979]

Will definitely be doing a back-set video soon here. The TK60HP I only really get to run when it’s regular operator is on holidays.

[@Andrew-Ponce]

@@canadianconcretepumper1979 looking forward to it. I’ve tried a few different acids and I can’t seem to use them right or haven’t found the right one.

[@samirbriseno4052]

hello scott! 2 questions, 1.-what is the difference between using water and using bentonite? 2.- I use the same pump control, but I don't know how to use the other buttons, do you know of a page on the internet where I can find the manual?

[@canadianconcretepumper1979]

Bentonite is much thicker than water and is far less likely to cause segregation of the concrete when priming through the boom. With very rocky/coarse mixes bentonite is the way to go in my opinion. With clean boom pipes, and properly mixed bentonite, it’s next to impossible to plug up on the prime with an otherwise pumpable mix.

[@canadianconcretepumper1979]

Your best bet would be to contact Putzmeister service support, they very likely have PDF files available pertaining to what you’re looking for.

Great man👍

[@newrealm9187]

Every time I’ve sucked a bucket I’ve jammed in my sweep 90. It’s fine except I like to hear the sound at the end of an empty system through my hose.

[@canadianconcretepumper1979]

I’m sure the rate of success really depends on the materials available in any given region. We’re fortunate here to have very “pump friendly” materials in our ready mix, so it works a charm. I’ve literally never had an issue with segregation, water-washing however is an entirely different story for me (probably was doing it wrong) 😂😂😂

[@AWS-lh3rn]

Great video I shall try this next time 👍🏼 do you get any cementy water drip on the boom when you fold up?

[@canadianconcretepumper1979]

No sir, and I will say that I was very skeptical of how clean this method would actually get the pipes. I can honestly say that we have more issues with slurry dripping out of the tip elbow on fold up when using our traditional sponge-water-sponge method.

[@bennycastro2190]

I stuff an old sponge in the end of my hose to keep cementy water off of the pump

[@canadianconcretepumper1979]

@@bennycastro2190 only reason I don’t do that is because we often travel dirty to the washout area or to the next job and If I get caught in traffic I’ll toss the pump into PTO and take a few stokes in reverser just to keep the mud in the hopper relatively mixed/not segregated.

[@bennycastro2190]

@@canadianconcretepumper1979 oh that's a neat trick, there's hardly anything left to drip after a good sponge water sponge anyhow

[@AWS-lh3rn]

@@canadianconcretepumper1979 I started doing the hard sponge water sponge method and it works great! I just tilt the elbow down and let it drain the slurry before folding. But I just suck 1 sponge when I’m running from job to job and do your method at the end of the day

[@750621116]

Why so difficult. Just spray 1 bucket of water in the ball catcher port after you fill te hopper with concrete. Boom in an arch and pump away at about 60%. When you hear the water falling in the last section slow down to 30%. Works every time.

[@canadianconcretepumper1979]

I would argue that it’s more difficult messing around with the prime-port (if one is so fortunate even to have one). Larger boom pumps we dump bentonite into the prime-port. Small booms just spray up into the cylinders. Other reason I minimize usage of the prime port is that the coarse threads on the bolt which secures the cap tend to round off rather quickly from screwing/un-screwing the hex nut. Not a fun time when you go to tighten down that clamp prior to a big pour and those threads finally decide to give up completely.

[@750621116]

@@canadianconcretepumper1979 We all have a prime port. Modified to open and close with a 3” clamp. I would attach a picture if I could. Even the putz M63 primes with 3 gallons water.

[@canadianconcretepumper1979]

@@750621116 that’s what I’ve always wanted on ours. We once had a 4” prime port utilizing a snap-clamp on our little 24Z boom and it was sooooooo much more user friendly than the bolt together clamp and larger port which come standard on most swing-elbows.

@@canadianconcretepumper1979 u may as well just fill your grout pot with water - lol (if u have one )

[@canadianconcretepumper1979]

@@garthhearns1980 I do indeed. Only use it when priming with bentonite (on the big-booms mostly). Couldn’t be bothered when priming with water as it’s quicker/easier and seemingly just as effective (with our mixes anyways) spraying water up into the barrels like in the video. The other issue I find with using the grout port all the time is that the coarse threads on the clamp for the cap round off rather quickly from tightening/un-tightening the hex nut. I wish they would use a fine thread as I think it would hold up a little bit better over time.
