How do I get my Shop Vac to suction instead of blowing?
Taking the cover off and making sure it was on properly.
Checking the hose. I have used it many times and not had this problem. Now it will just blow. NO suction.

I have no idea just what reverse suction would be or how to get it from ANY vac. If you're looking at getting the blowing air from the vac instead of suction, then simply move the hose from the suction end to the exhaust end.
Have you checked the hose for clogs or leaks. Clogged and leaky hoses are an area of concern with any central vac. Unless you hose has a hose sock, then wear and tear from constant rubbing on floors and other surfaces will result in holes and cracks. Pulling the hose can also result in leaks where the hose attaches to the handle and intake connector.
Mix some dish soap with water.
Use shop vac to blow air through hose, with other end capped or "clogged".
Apply soap solution to each end of hose.
If bubbles form, this indicates leakage. Hose will need to be replaced.
If this is an Electrolux, start by testing the suction at the inlet nearest the vac or at the 30 degree elbow on the left. If you have suction there but not elsewhere, and can hear the vac running when the hose is plugged in you have blockage in your main line between the vac and the rest of the house. You should first test the hose, then the inlets one by one. Drop a quarter into the handle of the hose and shake it through to the far end. If it comes out your hose is clear. Next mark a tissue with a number and **** it into the hose at each inlet, checking the bucket to see if teh tissue has claered the lines. If none of the tissue make it to the bucket, , get a shop vac, open the inlet nearest the vac and **** the obstruction backwards out the inlet. As blockage clears you will hear thinks moving in the pipe. Post back with results
There may be a blockage on the inside of the vac. I have had this happen to me a couple of times. The first thing I try to do is to make sure the beater brush is turning. If it isn't turning the dirt will not go into the bag. The other thing to do is to take a shop vac or something similar with high suction and see if you can suction out your hose. There may be something so high up in it that you can't see it. The last thing I would try is to take apart the inside where the hose connects to the bag and make sure that nothing is up in there. Try the shop vac first....this has always worked for me. Good luck.
first can it pick up water if so you put take the hose on suction and wrapp a rag around the end so you get full suction in the drain and turn it on.if not hook the hose up so it blows instead of sucks,do the same thing with a rag around the end of the hose and seal the hose in the drain,then turn it on.if you have a shop vac that will work better
1, Does the blower (discharge) side blow bunches of air?? Yes: Something is clogged from the bag to the hose end. Try blowing out the hose from the discharge side. Or: The bag is not properly seated. Make sure that the plastic piece is properly inserted into the bag, and properly aligned and locked in place with the suction intake. No: Something is wrong in the motor/fan assembly. 2: The hose has a plastic cover on the end farthest from the unit. Make sure that this cover is closed. If it is open, your suction will go way down.
