Pump was pumping water good. If suction hose happens to leak air and the pump continues running, let's say, some hours. Is there any damage? Thanks

Thanh,Yes, rhere will be damage. The pump has a plastic impeller that rotates and moves the water. If the pump runs for hours without moving water the plastic impeller will get very hot melt or bend and break. Also, there is a seal on the rotating shaft that will get very hot and be damaged. Sorry for the bad news but you must be very, very careful with the installation and make sure all connections do not leak.

Depends how long it was running without water,it could build up some heat if the impeller is plastic it could be mishaped and not pump as good!

When the pump runs "dry" heat can build up and ruin both seals and the impeller. Now in saying that my pump has run dry for several hours and there has been no damage. I would not make a habit of that though. Prime the pump and close off the air leak and try it, chances are it will work.

As a general rule, no pump likes to run dry. The water cools and may also help with lubrication. Sucking a little air might be OK but running dry is not, at least in my book, and that goes for any pump unless they expressly say it is. If you fix your leak, power on and and it pumps water without leaking around the shaft, you're probably OK.

a little air leak is ok -- it just needs to keep pumping water to stay cool -- if it ran dry, its probably damaged

hi therethere is a chance for damage, depending if air leak is so big, that the pump run dryif moderate leak, and there was never lack of water, so the pump never run dry, i would suy no damage.i hope this answer help you.

I believe so. I bought mine for a different application and I did not lose air when I disconnected it.As to the pumps IDK

Our problem was with the "fit" of the tank where it seated/sealed with the suction system. The vacuum pump worked. I have found in the past that when a major component of a lower end vacuum cleaner goes bad that repair is as expensive as replacement. Our Bissell now works ok after some adjustment and I will modify my previous criticism. I hope this helps to avoid wasting time and money.

Hi, It depends which fault code you have. I had a pump that would'nt come on. I tested the system and found the pump seized. But the main problem was the rear air system shocks leaking causing the pump to run excessively. I replaced the rear shocks and pump.Hope this helps you.

a very similar thing happened to me, I did not feel that it was worth the bother to send it back. we had ours for 3 days, and it burst. I cant give you an answer for them. I would not want another one. the first one was enough for me! I wonder if the technology on this type of hose is ready for the market.

I do not have that issue though. I purchased for underwater usage and it works fine. I think for some people that not work might be due to the seal of the wires into the pump. Double check before you use it and put some silicon or hot glue to secure it if that is the case.

I don't know if an out of balance condition could affect the pump but it is possible. If it is leaking at all, then replacing it is imperative. It will only get worse. Try searching the internet for a video on how to replace it. Then you will have a better idea of all the affected parts.

I personally do not leave the pump on when not in use. Grey water flowing by gravity should go thru, but if there is any debris, it may stick in the pump.

I drain mine after every use, so it hasn't been left charged overnight. I have it hooked up to a power draw bar on a mill, so there are a lot of press fit connectors and small air hoses in line that I would suspect of a leak before the unit itself if I were to test it overnight. I did test all of the seals on the compressor when I first purchased (soap and water test) with no noticeable leaks.

When I rinse mine with water and dry it for 24 hours it has really good suction.... That doesn't sound right. Maybe you could try a new filter to rule that out, but to me it sounds like a problem with something else in the vacuum.

Visably check the threads. Also the galvinized plug in the top is usualy not tight, could the leak be from there?This is by far the best pump I have ever worked with but the threads may be visably defecctive.

I have left the faucet on in the past but try not to. I know how damage a burst hose could cause. My suggestion is to not leave the supply hose pressurised (faucet on) whenever possible.

Hi, you might want to unscrew the bottom to see if it is clogged but first I would remove the hose and check there. I have had little objects get caught there and it would loose suction. I have 2 of these and have had the one for 5 years now and love them both. Hope this helps

After rolling the hose up twice it started started to leak water big time. I could never roll up a 100ft hose completely as avertised. I put it in the garage and have never used that piece of junk again. Bob

I just overheated mine the other day, pumping 4 tires from nearly 0 pressure. Let it sit for a few hours, while I did other things, came back and finished the last tire.

Yes . I let my pump run for about three days with no problems. I used it to remove water from my swimming pool cover .

I had the problem with my pump continuing to run after the pressure should have shut it down. I called shurflo and they sent me a new pump. My old pump was less than one year old. Warranted for one year. Low battery can cause the same problem too.
