Hush - Insufficient suction

You need to approach this step by step. If you have insufficient suction at all locations you need to check as follows:
1. Hose, drop a coin through from the handle to the wall end, with the hose detached from the wall. If the coin goes through from one end to the other the hose should be clear. If the coin stops it will rattle inside where the obstruction is if you gently shake the hose you will feel it through the wall.Obstructions in hose or pie need to bee **** wards out of the hose or pipe.
2. Vac. Go to the vac itself and see if the onboard inlet has suction. If it does your problem is beyond the vac. If not your problem may be a leak, either a broken inlet, with a cracked or sagging door or jammed hinge, a clogged intake in the vac, or damage to the pipe within the house or a twisted gasket where the pail of the vac secures to the body, or an issue with the motor itself..
3. Take the hose, inlet to inlet and check all locations in the house. I mark a tissue with a number for each inlet and plug in the hose, one inlet at a time. If the tissue makes it all the way to the bucket from each location, that means the branch line for that location is clear. I work from the closest inlet away to the furthest checking for tissues one inlet a t a time. This will help pinpoint location of any blockage in the main line.
4. If you have had any renovations or painting done it is not uncommon to disturb the seal behind and inlet or pierce your piping with a nail or screw. Check for all these and post back to say waht you have found.
