eads 14 Report post Posted January 25, 2006 Had the pump for 4 months. Only chlorine was drawn through it. Getting ready to clean a roof a few days ago and no suction. Cleaned the diaphragm out and assembled it backed together and still no suction. The motor runs but no suction. Any suggestions? Share this post Link to post Share on other sites
Russ Johnson 141 Report post Posted January 25, 2006 Probably the valves...either debris or got dried out. Check them good for little pieces of crud holding them open. If you can't find anything, try putting a little oil on the rubber flaps and try running it again. Share this post Link to post Share on other sites

Don Phelps 85 Report post Posted January 25, 2006 I've still got the 3 gpm ShurFlo (new, in the box) that you were interested in about 6 months ago if you need it. Share this post Link to post Share on other sites
Beth n Rod 1,279 Report post Posted January 25, 2006 do you have a micro mesh filter on the end of the inlet line? If so, check to see that it has not become clogged. If no filter, perhaps the line has something in it obstructing the flow. If that is not the problem, then your diaphram could be damaged. Rod!~ Share this post Link to post Share on other sites

BigPete 14 Report post Posted January 25, 2006 If the motor runs, the switch should be ok, or at least "ON". Share this post Link to post Share on other sites
eads 14 Report post Posted January 26, 2006 After taking the diaphragm apart I found that there was a lot of sand in it. Mainly in between the spring and the white cap covering it. I figure that it was sticking. But it still not working. Share this post Link to post Share on other sites
