Title: CWEV placement
Post by: Thunderhead on June 22, 2012, 06:44:10 PM

hi we have a situation where we cant get a drain out for the CWEV we have enough height at the top of the cylinder to be able to run a drain line for the TPRV...Are we able to under the codes raise the CWEV up to the height of the TPRV so we can run a drain for the CWEV by way of a standpipe or repiping the main feed up to the height of the TPRV installing our valve gear and then dropping back down to the cylinder entry point?...have not come across this situation before so just throwing it out there to see if anyone else has come across a similar situation...cheers thunder.

I dont see why not - as long as the cwev takes its normal position in the valve train assembly, throw a tee and iso valve on the hwc inlet, are you still able to get hose out to drain it?
