Greetings, Gary
Thank you for this post and for the knowledge that you have shared on this forum. I have gleaned much from you (and all who have contributed).
It has been about eight months since your update and I am wondering if you have any more updated information on how your system is working.
I have been using two Feins on four valved zones for the past several years, but one of them has now melted all of the internal plastic parts for the second time. Rather than the cost of another repair and another failure, I have ordered two LH 6765-13 vacuum motors from Ward and I am preparing to build a two motor box similar to yours with manual switches.
I have read every post that I can find regarding vacuum boxes and have seen two schools of thought regarding filtration on the intake side of the vacuum system. Are you and the others that you have built for still running without intake filtration?
Kind regards,
JIM
