Have removed all the non return valves now , sweet !
My system only gets fed with pure too Dave , i still keep my di in the van for that final polish ,
And the varistream is the dogs danglies , i said in a prior message about having killed 2 batteries , well i used the worst battery of the lot today , it only usually runs for 3 hours , and is caned by 12 , today i used the same battery from 9 to 5.30 , no loss of pressure and its still got loads of life in it !
ITS OFFICIAL , VARISTREAMS WILL PROLONG THE LIFE OF YOUR BATTERY !
