I had the external water supply dis-connected for a while, with no problems.  Then my wife and I
got tired of the westy faucet and we designed what we consider a 'better' and very cheap
alternative.

If for some reason, you get water comming back through the external line, then just plug that line
with a bolt and clamp.
