Re: [DIY] Water Level Indicator for a Shop Vac?

 

Why not just use the water pump primarily to drain the water out of the tub instead of via a vacuum pump first?

Also, you can install a one way drain valve (a check valve) from your vacuum unit so that it will automatically drain the accumulated water when the vacuum motor is not running. The presence of a vacuum would keep that valve shut. No need to wait till the water level is too high to evacuate the water out of the vacuum unit.

Ok, this may sound a little strange but I'll toss it out there.

I have a 16 gal Shop Vac with an auto pump that pumps out the water via a garden hose as the vac starts to fill up.

I use it to help drain our hot tub and it works great.  The only problem is, the suction is much faster than the pump

that pumps out the water so it fills up and shuts off before the pump can drain the vac.

What I do now is try and time it to so that I pull the suction hose out of the water before it completely fills up to allow

the pump to catch up.  A major pain since I'm not always accurate.

What I'm thinking of doing is drilling a small hole into the side of the vac and putting a small plastic tube along the outside

to act as a water level indicator.  But before I do that, I don't know if it'll work on a vacuum and I may compromise the

suction by doing so.

Anyone ever do this or know of any shop vac type of device that has this from the factory?  I would think there's a valid

reason that manufacturers don't have this on wet/dry vacs although it sure would be handy.  I searched on the web and

didn't see anything specific to doing this.
