I have a Transcrete trailer pump, being pumping fine for years.. [Stilll is] Just recently it has started pumping then  goes into reverse and then back into foward really quick keeps doing it until you manualy pump [jog] it for a while then its fine for the rest of the day???

Any help would be appreciated .

{pumping pools with 2 inch line }

Did you call the guys at Transcrete, they are some of the best and they know what they are doing.

Sound a bit like one of our pumps but than different ;-). When you pump very slow it often just takes 1 stroke reverse and than forward again. Very irritating when you have to pump slow. No one understands why and when the manufacturer is there to look at it it ofcourse doesn't happen.

Thanks,, I have spoken to the guys at transcrete they suggested a few things witch we tryed but no success..

Thanks again......

did you change the change over relay.

Thanks for your reply, Yea we changed it a few months ago wouldnt need to do it again yet would I???
