i have a pb4 booster pump also has lr51044 on it, anyway i have just moved into this home and this pump is on our outdoor pool, its not sucking the dirt out of the pool very well and a guy said i needed to replace this pump but another man at the hardware store store told me about this site as i was looking at other sites and none of them was helpful at all...can this be worked on or does it need to be replaced?
