hi ukaps me again one thing after another i know. so heres is the problem this time. ive got my self a 10000 sequence pump for my 750l tank. at the moment im running a draper 9000 through a 22 mm pipe (i drilled after a pint or two). this seems to be giving me good flow round tank. leaves are all moving and drop checker is green.so im wondering when i change to the sequence pump and make a proper spray bar http://stores.shop.ebay.co.uk/Clear-Pla ... QQ_armrsZ1 do i still use the 22mm pipe for the spray bar or do i increase the size as not to restrict the flow. if so what maxim size do you think would give nice water jets ive yet to buy any plumbing for this pump yet but will be doing so this weekend. thanks for any advise always welcome.
