Does any one use a tip hose that is longer than 12ft? Whats the longest tip hose that you guys run?

Usually 10ft -12ft but have ran 25 ft 3 1/2 in hose and a 30ft 3in hose

12' hose 4 1/2''

some manufactures have a 13 foot tip hose as standard on some machines.

we use 20 foot tip hoses to pump through red iron, or over houses. they work well but watch the wipp

i have a pb job where i have to use a 16 foot 4 1/2 inch hose to get down past the rebar in the core walls. if your mix is a good one and wet it will run great i have pumped a steady 140 yds an hour thru it many times without it whiping hard.
