Help required with Saniflo diaphragm - ZERO EXPERIENCE !!!

[Ray1000]

Our Saniflo has been failing to stop automatically for some time, just a gentle kick would solve it until recently when it would run forever.

Stripped and cleaned and removed the diaphragm. Found the micro switch works as it should until the diaphragm is replaced - permanently compressing the switch.

Is this how the diaphragms always fail, somehow gradually getting closer to operating the switch without the help of water pressure?

Thank you

Needs a new diaphragm. I have them in stock @ £14 Incl p+p

Thanks JP I was trying to find out if they normally fail in this manner?

 

[Ray1000]

I concluded the diaphragm has been "drying out" over the last 25 years becoming smaller and less flexible, not allowing the plunger to fall away from the micro switch.

After heating the diaphragm with an hair dryer and massaging it with WD40 it appears to work perfectly normal.

Just need to re-install it in the morning.

Good luck.

Thanks JP, there was a fine layer of sealer on the diaphragm from new, is there a need to replace it with anything?

The only thing that I can think might work and that you can buy off the shelf would be LSX or Red Hermitie and if the old one really is 25yrs old then there is a good chance that it will fail again after the massage allowing water into the electrics.

Thanks for the Red Hermitite suggestion JP, it was the perfect sealer.

The diaphragm is much more likely to stop operating the switch before it lets water into the electrics.

Thank you again for your help,

So now you are telling me eh, I have 20yrs experiance and you have zero, anyway I`ll leave you to figure why you are wrong.
Have a good day.

I’m sorry; I’m trying to be as courteous as possible.

Is it me saying it will fail to operate the switch before it leaks that’s upset you?

Please let me know if I’ve missed something, rather than leaving me to figure it out

Thanks

You wrote ... I have 20yrs experiance and you have ZERO

I read the previous Saniflo questions before posting mine, so I already knew you had a vast knowledge of Saniflo systems, and even more so since you have pointed out it stretches over a 20 year period.

You are taking offence at me saying my reconditioned diaphragm will fail to operate before it leaks water - as I have ZERO experience.

I’d be surprised if you have ever reconditioned a diaphragm, always having a new one to hand, and you wouldn’t need to risk it anyway, whereas I HAVE had some experience ... albeit only yesterday.

I say only yesterday - that is if you discount the sixty four years since I started my Mechanical Engineering apprenticeship.

In the intervening time I’ll have worked on - supervised other people working on - and been legally responsible for thousands of pumps ranging from one’s you could hold in your hand, to ones the size of your kitchen.

No, speaking from experience the diaphragm in our Saniflo is a lot more likely to fail to operate over time than it is to allow water in.

Thanks again for your help

Problem solved, Saniflo continues to work as it should.
