Absolutely! Always helps to pound it through for a couple of minutes prior to pumping out and sucking back. We do sooooo many of these slow pours, hard ball-water-soft ball has really helped in mitigating what's shown here in the video.

@@canadianconcretepumper1979 in my part of the world where we pump most of the mud is 4000 psi but on the average of 6000 to10000 psi the water to cement ratio is to high to get a ball back cleanly but as a last resort. It's why I resurulate . Not olny can I loosen the set mud on the hopper but reduce the amount of cement to water then water wash and further degrade this ratio. On a different point I love how easy it looks to wash those putz hoppers !! I run schwing and they can be a real bitch sometimes

Especially slow pours you gotta recirculate fast before blowing out boom to break up build up. I ran 20m for few years I would run into this problem every now and then... started recirculating before blowing out and never had problem again.

Absolutely. I too am almost embarrassed to admit that it's become just part of the job for me 😂

something that we do every time with ours, we suck one back somewhat slower, open the back end up once its back, then get the tip section positioned so we can put about 20-30 gal of water in, hard/harder sponge, and blow it out the rest of the way with air. at most, ive only ever seen just a very small amount of sand/fines in an elbow when replacing gaskets. I'm sure this isnt ideal in EVERY scenario, and it is a bit messy, but it does work very well for us.

Most of our machines have the ball-stopper built into the prime port, which makes it even easier as we don’t need to open up the backend to retrieve the first sponge prior to sucking back the second. Agreed, sponge-water-sponge is a highly effective method 👍🏼

use washing cylinders and when finished put the water in before pulling the cylinder. only good

Yes! Some of these “exotic mixes” are absolutely terrible in terms of leaving residue in the pipes. This is why when someone says “I clean out this way and it works every single time” I have my reservations. We are in a constantly evolving industry and it’s paramount to adapt an evolve along with it.

I also never had an issue when I sucked a square sponge back in the day. I always took reducer off put water in and rolled up my wet 12" square sponge and just sucked it back at moderate rom 1200 and maybe a 2 on the dial. Never had more than a mm or so build up when I rotated pipes

Done properly a single sponge works 99.7% of the time. We had a project pumping bridge decks in which the contractor had two of their own pumps with 15+ year veteran operators. Around the 2 month mark of the deck portion of the project (high cement/high chemical mix), they began having pumping issues, only to find that both of their machines had literally 2+ inches of buildup in the boom elbows. These were guys swore by sucking just a single square sponge. Same project we would put 3 sponges through our 58 meter and the pipes would still be creamy. Really depends on the mixes which you’re pumping.

I had this on a used pump the company I used to work at bought. The funny thing is the previous owner said he had to help another guy in the town he was from suck a sponge because his pipes were half full. Once we bought it I had a terrible time priming. It would always segregate whether I used a slick pack or just water. So I took a deck pipe off and it had almost 1" in it... I was pissed off but once clean it worked all the time after that. Ever had your pump stall trying to pump shit concrete? I have

Much appreciated brother. Thank you.

Very interesting info on this one! I’ve been running a 33m-5ZZ for the past month. First time running a 5 section Z fold boom. Hated at first, but now I’m getting comfortable with it and I’m enjoying it. Question for you, do you suck a sponge on an A frame or do you fold up and put it in the cradle and then suck the sponge? I’ve tried both and have had about the same success rate. I’ve tried putting the boom up in the air too. Not a big fan of that one because I feel you can segregate rather easy, but this is more of a panic move. More of a “gett’er home” because this concrete is getting old…fast! Anything you can share will be appreciated 👍

I typically suck back in either A-frame, or Z-formation. Certain situations (low clearance/indoors pours) I will suck back in the cradle but in my opinion it is less than ideal (I have had issues with buildup in the pipeline after sucking back in the cradle). I apply the same theory for sucking back the sponge as I do for priming: keep as many sections vertical as possible such that the water cannot run ahead of the sponge only cleaning the bottom half of the horizontal pipe (on the prime the intent of the water is obviously lubricating the pipeline rather than cleaning it). A-frame is king, Z-formation also works well, sucking back in the cradle is my least favourite option and last resort. Thank you for watching the channel. The comments are very much appreciated 🙏

@@canadianconcretepumper1979 no worries man. I find these videos very educational for an operator who is into the more detailed operation of a concrete pump. These are fairly cool machines, but there is a lot more to it than unfolding the boom and turning the pump on and off. Anyway, I think I’m gonna start putting my boom in an A frame unless I can’t. I’ll take your word for finding out that you have build up in the pipes after sucking a sponge with the boom in the cradle. I’d hate to be “that guy” lol

@@stephenknowles3934 It’s one of those rare situations where you actually want the concrete buildup to be a little bit thicker in order for it to fall off when you bang the pipe with the hammer (3 lbs mini-sledge is my weapon of choice here). If it’s just a thinner film of concrete the hammer technique may not work as well. Thank you for watching the channel brother, I do appreciate the support 🙏

I just replaced my entire pipe kit last Friday and the first two jobs I had I couldn’t get the second sponge back all the way to the ball catch on the swing 90, the first ball made it but not the second one. You think maybe my gaskets haven’t sealed up all the way yet after replacing everything? The first two jobs after replacing the pipe were small jobs maybe 80 yards combined between the two. I just ran the gaskets fry I didn’t seal them with silicone or grease as I’m not a big believer in the reasoning behind that idea. I ran a hopper of water through to push the sponge out just in case and since then I’ve put 700 yards through the kit. After a 600 yard pour two days ago I was able to suck the two sponges back no problem. Do you grease the swivel gaskets or fill them with silicone caulking when you replace them?

@canadianconcretepumper1979

What I have seen with the larger 6” round balls (if that’s what you’re using) is that they are large enough such that when sitting in the transition door they can actually obstruct vacuum from pulling that second sponge back.

@canadianconcretepumper1979

I agree with you in the belief that silicone/grease in the gaskets (aside from the swivels) is mostly just mumbo-jumbo. I only use a light spray of WD40 on the outside Of the gaskets as such that the clamps don’t pinch the gaskets. What I do firmly believe in is whenever installing a new boom pipe kit, filling the hopper with water and sucking back a sponge with a nice, fat bucket of bentonite (pudding consistency) in front of it to fill any voids in the gaskets.

Very specific mixes is what has caused us most all of our issues in the past (typically high strength/high chemical mixes poured at a slow rate). This one I’m betting some naughty operator sucked back a soft sponge through the 4” taper at Mach 1 speed.
