Don't know if other Sapphire owners....

[NobleCarpetCleaners]

have waste tanks with no sight tubes but I'm guessing it's common for them not to have a sight tube that can be seen easily. My White Magic did and I relied on it.

Today at approx. 235 hours on my SS370 the Hartwil god da.. float switch decided to snooze and not shut off my machine. Just lovely seeing dirty soapy water spew out the machine. Blower belts smelled awful bad. Ya know from the first dam day I used the machine I missed my waste sight tube. Well I'll install one reallllll quick and my advice to others is consider a site tube on your tank. The legendary big dog ex-Prochem engineer behind the scenes at Sapphire screw you dude. You ended up hazarding our machines on a float switch that doesn't have the best rep in the navy. I had 2 fail me in the past on my older machine. Use to watch the level go up to see if it would shut down and nope. Always relied on my sight tube. Not having sight tubes I think is a Prochem bad habit. Guess you should have left that one behind......

Ahhh..

The days of the Comment Card are so missed by some.






I'd love a sight tube as well.

You can fix that in 30 minutes.

 

[hogjowl]

Never had that problem on my TCS units.

BAHAHAHA

Splain please

As Lee mentioned a simple low cost fix. I never go out to the truck to view it. I'm more concerned about my fresh water level.

I've not had that many issues with the Harwell. Although we did have one break last week. On the inside of the tank, forst one I've ever seen break there.

 

[Mikey P]

I've had atleast 5 fail over the years

 

[Lee Stockwell]

Empty tank, remove dump valve. After measuring, drill hole in top of pipe fitting valve screws into.

Drill similar hole in bottom of top fitting vacuum hose connects to. Insert matching barb fittings into each hole and attach clear tubing and float sight ball.

 

[Desk Jockey]

We used to snap them off with out hoses. Our distributor fabbed up a shield and haven't replaced one in several years.

 

[Lee Stockwell]

You can dispense with the top fitting, if you use amply long tubing and secure the top so it doesn't leak.

MB is to manufacturers what Yelp is to carpet cleaners.

what Lee says

I made a video for Jim Martin once...but I must have deleted it

I've complained about those switches a lot a sight tube doesn't help to much if your cleaning. The machine lose vacuum when the water level gets high even before it shuts of. I can tell when I'm close my guys haven't got a clue. Unless like you there's a water fall.

 

[Cleanworks]

ever hear of an apo?

.

 

[SamIam]

Apo uses harwell switch to

 

[Cleanworks]

instead of a Harwell switch, go to a simpler float switch, like a mercury switch. I have one in my old plexiglass apo that is over 20 years old.

 

[Desk Jockey]

Personally I've had better luck with the Harwell than Mercury floats.

 

[NobleCarpetCleaners]

or the sight tube I just installed so I can rely on myself

 

[NobleCarpetCleaners]

pics of installing a sight tube on waste tank. You need a 9/16" drill, 3/8" pipe tap, tap handle or socket and ratchet, 1/2"barbX3/8"mpt elbow, 1/2"i.d. clear hose (thick) and a float. For a float I sniped off a piece of 3/8" black thermoplastic hose. If you're nervous about cutting threads, practice on piece of scrap the same thickness of your tank. Then no guessing on level of waste.

Nice job!

Can a harwell be fixed if there no clicking sound I know there magnets inside I've seen Jim Martin post a pic of one opened up to. @Jim Martin

Yes you can buy the Harwell micro switch but for the cost I would replace it, if you are at ice come by the zipper booth and i will let you know where you can get 3 Harwell assemblies for the price of one.

 

[dealtimeman]

I have done it close to the same as noble has done it with exception is I use threaded pipe nipple fitting into tank with a sharkbite threaded into it and the clear tubing just slides into the shark bite on both ends, thus no way for a hose clamp to be pushed or forced off.

you can get the entire float switch...or any part you may need directly fro Harwel..

float...switch.... shaft..casing..etc...
just give them the number off the one you have...

that's another problem some have...Harwil floats come with different size shafts...floats...and number of magnets ( which is real important )..pending what you are going to use them for...
they last for years..it is rare to have a problem with them unless...the wiring is over loaded and it is over working the switch...connection is loose or dirty and it is having to draw the circuit to hard...wrong float for the wrong area or application...
If the one you have has been working and it just wore out...make sure that you give them the number off the one you have.....

 

[SamIam]

I've gone through two in less then 2 years maybe I need one that's beefier.

Where's the beef?

Taco's getting plump. Talk to him.

Is he sending you photos oR what?


But hey I'm not saying there is anything wrong with that.

You can fix that in 30 minutes.

That doesn't count the time needed to climb in and out of van.
