The other day i worked on a pool the timer that controls the filter. First i went to my local elec supplier i show him the timer he brings me back a box and says this is it i say ok . (I should have looked at it BUT I DIDNT DUUU ). When i get back to the homeowners and open the box well guess what wrong timer . It was the kind a rocket scientest had to set. Well to make a long story short I lost time and money . Wanted to make the supplier pay but cant do that the homeowner knew it was the wrong one so i couldnt make him pay. My question is Y do we have to eat it all the time?
