Need help with 870 chem injection.

[Nomad74]

Looks like the O Ring on the high pressure side is chewed up. I’ll flip it around and get through this job.

 

[Nomad74]

Holy crap! That was it. I flipped that ORing around and it came to life. I think it will get me through this job. But I’ll stop at ace hardware on the way home and replace that ORing. Thanks a million guys!

Sweet.....thats like the check valves being stuck open..its allowing it to blow by and not building pressure..

 

[Vincent Feehan]

change the diaphragm while your in there, 500 hours is usually all they last

Good to know, if i ever get an 870...

Yeah, I have been getting blow by when the switch was turned to the off position. The shuttle would just slightly vibrate. That would explain why.

1400 hours so far. Is this something I can get at ace hardware?

Likely a tiny air leak.
@Justin Stockwell has this machine.

If it is an air leak, it's most likely not a hose. It's probably a brass piece like an elbow or hose barb(like behind dwyer meter). Over time water and/or chems eat away at the brass right by the threads(thinnest area).

Prime hose back to the dwyer meter, hose going into meter(bottom) is the one that fails. Check it!



I've unfortunately replaced just about every piece possible at lest twice. I used a certain rinse a while back and would eat the brass in 3-5 months!

 

[Nomad74]

I guess I got lucky being able to pull out one last job with that ORing. When I took it out to replace it, it fell apart into 5 pieces. It served me well.

 

[Nomad74]

I wish just one time in my life I could make a post without having to go back and correct typos! It sucks having fat fingers.

View attachment 77047 Buy a bunch. Every time a goofball is cleaning tile at 1800 psi, it nukes the diaphragm if they forget to shut the ball valve that isolates the chem pump.

Any chance you can throw me a link for these diaphragms?

Is that the same POS you'll be bringing to Vegas?


Do you still have the Chemtex?

Very hurtful.

And it’s an Amtex, not Chemtex. Idiot.

When you fall asleep I’m going to run my nailess fingers on your lips and whisper in your ear how much I love my Moonbeam hose reel.

Who makes that thing? Swivel looks to be in a weird spot.

 

[Mikey P]

Dangnabit.

@Jim Martin, after looking at the diagram you posted, I am missing one Oring completely. The low pressure side is totally dissolved. Glad I bought a few extras. This was my first time getting into one of these pumps. I appreciate the help.

Wouldn't car part stores like summits racing carry the o rings?..they are usually rated high pressure/temperature resistance

Near misses

Damn guys. I decided to check my diaphragm tonsee how it looks. It looked a little roaches and about to go out. I got 1400 hours out of this thing so I can’t complain. Glad I ordered a new one last night. It’s still working but looks like it could give up any minute.

 

[Jim Martin]

after seeing the O-ring...I am not too surprised.....

 

[Nomad74]

I put it back together and now its not working again! Ugh! I think I also crushed a check valve plastic housing when putting it back together. I think they are okay because they passed the suck test. Going to see if I can get new parts today.

 

[Nomad74]

I just ordered a check valve kit. $34 and $22 two-day shipping. My local guy only has the diaphragm without the lip. I'm going to try tha until my new one arrives. I should have never taken it apart to check it!
