Need help with 870 chem injection.

[Nomad74]

I hope I ordered the correct check valves.

Would this be beyond use? I probably made it worse by taking it out to check it.

 

[Lee Stockwell]

Keep spares, that means more than one.

 

[DAT]

Good to know

 

[Nomad74]

I ordered 5 spares. I should have it by Friday

 

[Nomad74]

@Mark Saiger , after watching your video I think I put that white disk in backward. I'm going to go flip it around and see if my injection comes back to life.

 

[Nomad74]

You guys and Meg aren't going to believe this. I flipped that disk around, put back in the chewed up diaphragm, and it snapped back to life. Ok, back in business. I don't know how much longer I have with that diaphragm but I have new ones on the way. Thanks for the video Mark.

You are definitely living on the proverbial "borrowed time."

....how many other things??

Well, I know my blower, motor, and pump oils are all good. my solution lines are pretty fresh. I stay up on those. I learned a lot about this pump over the last 24 hrs.

I should probably check my APO rubbers. I'm almost afraid to look.

We have extras on each van and by fortune can swap them out if and when needed on a job site

Dear Lord..dont touch the APO..that thing should last year's trouble free...just flush it out with clean eater now and then...your o-rings and diaphragm on the chem pump are being desolved by your rinse chemical...over time it starts to deteriorate them...between that and the high PSI when cleaning tile..1000 to 1500 hours is about what they are good for......the only thing that goes wrong with APO's is when they are left sitting to long and not flushed out...or if there is no in line filter and crap gets up in the check vavles...other than that they are pretty bullet proff....

What could go wrong

Did you see the valve on his pulse pump? He can turn it off in high pressure use

yes.....I noticed that it was isolated in the picture....that's the way they all should be.....

The manual says anything over 1200 PSI the pump should be turned off and isolated. I have never ever turned it off since I never go over 1000 PSI. I,m usually around 900 PSI on tile.

 

[Pioneer Floorcare]

If you don’t need pulse injection it is the better way to turn off flow, so you aren’t wearing the rubber parts

Worn rubbers are never a good thing.

do you use or think you need a rinse for tile.....I would be shutting it off every time..........

 

[Nomad74]

Yeah I leave the pump on but the chem switch to off with tile. I never need to go over 900-1000 on tile. I don’t like blasting grout. The heat and chems seem to work for me. But maybe I’ll start turning the pulse pump off just to save wear and tear. But I can’t complain. I got almost 1400 hours out of it.

I know I said it before. But thanks to all you guys for helping me out. I learned a lot. Turns out I didn’t need to remove the muffler.

You should score the white disk as this will make the pump work better and give a bit longer service life to the rubber diagram.

Yupp

 

[Nomad74]

For the record. The 870 ran all day at the RMH today. It was a beast.

 

[Jim Pemberton]

You worked pretty hard and reliably all day yourself Damon.

It was great to work with you (and several other MB I hadn't met before), and get to know you better.

I'm looking forward to seeing you at class in March.

Special thanks to Davis Pailliotet, Ely Young, and Scott McKay, who unselfishly slaved over rayon velvet and other challenging fabrics with me while others worked on the floor surfaces.
