reactors plumbed independently

Zac and Greg R,

Aren't the reactors already set up so one can be valved off from the 
pair so that only one pump is used?

I may be wrong, but I believe only one eductor is in place.

Also, if there is only one water heater available to heat oil, don't you 
just need one reactor for this weekend?

If you are going to do any replumbing of a permanent nature, please 
email me directly so I can send you a copy of the reactor piping diagram 
that we reviewed at the last siteplan meeting.

Thanks,

Felix
