Sup guys, its Krys. I went to Gardiner pole systems.co.uk and bought theirs 100psi water pump and plugged it into my trolley system. But when i turn everything on it seems to work fine, i got nice steady flow no problems, but the noise that is coming out of the water pump is concerning me, i have little knowledge about how water pumps supposed to work. Its like constant repeating clicky noise, i have liquid logic controller with flow rate setting at 20, if i increase it to about 80-90+ the clicky noise is gone but obviously i cant work at this rate since my 25l barrel will be gone in seconds. I do use a strainer between my barrel and pump. From barrel to strainer i have 8id hose, from strainer to pump i have 5id hose, and from pump to my pole i have 5id hose. And the barrel is raised above the 'pump-is-a-box' setup. If anyone does know if the clicky noise is right or not i would be very grateful for help. Thank you.
