Hey Perry .Dont get discouraged great question and one day someone will be wanting to know the same thing ..When you first work with this hydro stuff it can be intimadating...I added an extra valve to mine ...I put tees in between the pressure and return lines .. mine is working fine..dont think it will work inline..If i remember correctley joe said these are closed systems so there wont be pressure on the return til valve is opened ....Hey lets get a tread started see some progress pics ...Cheers lou
