Hi I just bought a Schwing 1000 trailer pump, my guys are kind of new at doing this and there having trouble with the clean up, whats the best way to clean out the lines? ive heard air is a way but its highly dangerous and ive heard not to do air, im not really sure...right now they hose out the lines, cant build up water pressure to get the ball through...any help would really be great. thank you!

how large is your hose system

3'' and 2''

should not have any issues with two inch hose, you do not have to run it fast. with three inch it takes a lot of water so elevate your hose with boards to keep from losing your prime. so my manual says to dump the hopper before you fill with water, it will leave a cleaner pump but a mess on the job. for two and a half hose i get one of those kids fun noodles and cut them at three inch. if you make up a 3/4 hose connection to a weld on fitting you will have a back up program.

A schwing1000 pump is a pretty serious piece of equipment so I would be very carefully running that machine if you are inexperienced. As for the clean up there are three main ways to do it on a line pump.

1 Water wash: break the system after you have reversed the machine as to eliminate any pressure in the system and put a sponge ball in the hook up your water fitting to the line and push it out. If you cant get enough pressure to push maybe you need a more powerful pressure washer.

2 Suck Back: Pump the hopper down as low as it can without sucking any air and the put the machine in reverse and put a ball in the end of the system. This works well if your line is running uphill, but can be problematic if running downhill. Be careful not to cut your sponge in the concrete valve. Also this only works if you have a short amount of system out because otherwise the hopper will overflow.

3 Air Blow Out: Can be very dangerous if you don’t know what you are doing. I would highly recommend that you don’t use this option until you have an experienced operator show you how it can be done safely.

thank you for the advice

I would highly recommend you find a experienced operator as close as possible to get your guys at lest 40hours of hands on training. There may be restrictions/local laws about where you are even allowed to wash up with water. As far as being safe as possible with that pump, do you realise that pump will make over 1100 psi of pressure on the line (say if you ever get a line plug?) The risk you are taking by running that pump with out at least basic training is huge in my opinion and leaving your self wide open for a lawsuit if the worst should happen. In my opinion if you are unsure about how to clean the hoses you have no business running the remote. 

Well they have been pumping for 6 months (about 35 jobs) just trying to make it a little easier cleaning up. thanks.

Hi Steiny,

The Schwing Call center has service techs on the line that can help answer these or other questions

Just call 888- SCHWING (724-9464)

I run 3 linepumps , and we usually water wash the 2" line and you  can waterwash 3" line also but it does take more water , air is really not a option assuming you run all hose, we do suck back at times but all your wear parts need to be in good shape , a blow out cap with a water hose fitting and a water pump usually will push a sponge through the hoses  also , their are many ways to clean them safely and efficiently , you just need to find the one that works best for you and your guys.
