I use that technic you show us in an another video and I just love it work nice no tap tap on pipe no sponge get stuck work very nice thank you .

We always suck it back through the tip hose, too much hassle taking it off because all our pumps have squeese valves

We’re most always tapering down to 4” or smaller (3” is most common on this little pump) right from the tip-elbow, so I typically just unclamp the 5”-4” at the tip-elbow and stuff the ball(s) in.

On your remote screen the icon on the right of POH is the air pump , when enabled it turns the airpump for blowing out on the pump that I operate, you start and stop the pump with the same switch you use to pump concrete with it.

All we have in the North American market is the line for the air-cuff. Problem with trying to use it for blowing out is that the air valve mounted to the tip section prevents mass quantities of air from being discharged (eg: blowing out line). Our older machines (pre-valve) we would do similar to what you do). European market gets all the cool options.

@@canadianconcretepumper1979 hello there, what determines whether I put the water before or after the sponge? I've tried both and I have lots of problems when I put the water in first, also a putz rep told me to put the water in after the ball.

@@TylerTimmermans best policy is to use two sponges and not put any water in front of the first ball. If you are going to do so, there’s many factors to consider (boom position, what type of material are you pumping etc…) before choosing to go that route. I’m pretty comfortable using just one sponge with a good amount of water in front of it, but it’s definitely not for every situation.

As Kieron mentioned, the best bet is to put the first ball in dry. I will often (and depending on the situation) just load water in front of the first sponge and call it a day. So many factors to consider (boom cannot have any residual concrete lingering in the elbows and/or horizontal sections of pipe), it also depends on the material which you’re pumping. For 10+ years all I ever used on our 40Z (4.6” boom-pipe) was one single medium round sponge with a pile of water loaded in front of it and I literally never had an issue and my pipes were always clean. Try the same method on our little 24Z however, and the pipes weee left with 2” of buildup. It takes a bit of trial, and unfortunately error, to find what is the most efficient for you. No two machines are ever really the same. All that being said, one sponge sucked back dry followed by a second sponge with several gallons of water loaded front of it is the absolute most consistently effective way to get a boom clean.

ive been seeing guys get slung all over the place by a line pump and air pressure cleaning out

Many people do not give air the respect it deserves, until after they have a bad experience with it. You can quite literally create a bomb by using air incorrectly to cleanout system.

Do you have any idea why a pump doesn t suck the sponge? It was bought recently and no service was done to it.

Sponge-water-sponge is my preference as well. I only posted this to prove a point that people LOVE watching the sponge go back. 😂😂😂

Puttin all that water in before the ball is only a good practice for a pump that washes on site. Our pumps run 4 or 5 jobs back to back without washing out. Sucking the ball back alone is all we do. If you had all that water in there it would rock lock on the next job

It's the same here. We wash out at the end of the day. After 4-5 jobs. We don't even suck back a sponge between jobs just suck as much back as we can and drive to next job usually within 30-40 minutes any longer we suck a sponge
