  • Water Flushing Pump

    Can someone who used a sump pump to flush there engines out for rust tell me what size motor your pump had. If I go this route I want to be sure it will be powerful enough to do the job. Thanks

    The $5 garage sale pump I used is 1/3 HP and 1725 RPM. Imperial brand pedestal pump.

        I found one of these for $40.00 last year on ebay.
        1/3 hp 3480 gal per hr. At 5 ft discharge level above pump, 3000 gal per hr.

          Model A Flushing Pumps ...... If Intended For Cleaning?

          One thing to consider is that the insides of an 80+ year old engine/radiator does not have a smooth, vitreous china surface like that of a normal commercial toilet which keeps clean with only simple standing water and forced water flushing action.

          For "positive" flushing, one would be wise to consider at least one of many chemicals to "chemically" cut through grease/rust/dirt embedded in the "rough", porous metal surfaces of cast iron and "rough" white mineral build up in radiators.

          In fact, in my opinion, introducing one of the best cleansing products like POR 15 Marine Clean accompanied by the mild action of a normal Model A water pump, could clean "rough"surfaces far better than connecting an 80+ year old Model A cooling system to (3) violent high pressure fire truck water pumps.

          Just trying to assist anyone on this Forum in sharing past Model A radiator/engine cleaning experiences.

          Well I found a guy on my local Craigslist that had some pumps for sale. After looking at them I decided to purchase a pool pump from him which I paid $40 for it has a 1hp motor and seems to work well.

            Does this have to be a sealed system and the pump primed to get it to work?

            I checked the pump to ensure it was pumping water, I believe it will do the job.

          Identify my water pump
          by Rumbler
          I bought a 1917 Model T Touring this summer and it has an aftermarket water pump configuration as shown below. This pump leaks water past the shaft and I would like to either fix it or remove and replace with original (no pump) parts. The engine is a 1922 vintage. Can someone identify this water pump and is it worth trying to re-pack the seal to keep it? My inclination is to return to the original...

          Has anyone ever seen a water pump like the one pictured? I was told that it came from Montgomery Wards?
          Is the grease fitting real or phony?
          Also, can anyone tell me about a "Bulldog" (rebuilt) Model A engine. Supposedly rebuilt in Turlock, CA.

          Anybody know what this water pump could be for? I thought maybe an overhead conversion but I can't find any that use a pump like this.

          Time to deal with my leaking water pump
          by thom
          The water pump on our '28 coupe has begun to leak again. I have tightened up the packing nut a couple of times but it's time to do something else. I thinking about one of the pumps with the modern bearings. Any disadvantages?
