Vacuum Switch Issue

[dboyes]

I have a Sealand VG2. I replaced the bellows, duck bills and vacuum switch. I did this because I replaced all the hoses and cleaned out the black water tank to address a smell issue. The smell has gone. I replaced the bellows and switch given they were old.

The vacuum switch, initially was turning off.

Now it will only turn off if I slightly help the switch, then the system is good and it keeps a vacuum for ever.

I decided to put the old switch in and try that, it also needs 'assistance' to turn off.

Any idea of what the heck is going on here???

Sounds like either a wiring issue or a defective vacuum tank switch. See #11 in the trouble shooting guide in your owners manual if you have one. If you don't, send me a PM that includes your email address (no way to attach anything to a PM) and I'll send you the trouble shooting guide. The VF has changed so little except cosmetically since Mansfield Plumbing introduced it in 1978 that the same trouble-shooting guide works for all versions, all years.

I'm too new to forum so it won't allow me to send private message, so this is what /I was trying to send.

Peg,

Hi, I have your book and years ago I phoned you for help

My email is deboyes@gmail.com for the troubleshooting instructions.

Wondering how this can be electrical when it does operate but just needs a little touch to the switch to stop it?

Thanks,

David.
