Q: I live in a condo building -- 3 floors, 7 units. In our storage units (right below my unit) is a water pump that was hooked up with the intent of helping the water flow to the 3rd floor. Everytime the pump goes off, it rattles, then makes a loud noise when it kicks off. The developers created a drywall box that houses the pump, which is surrounded by isolation, but it doesn't seem like it helps the noise. The pump also rattles the pipes that connect directly to the pump.My question is -- is this rattling normal for a standard water pump? If so, is there anything I can do to help cut down on the noise? If this is rattling is not normal of the standard water pump, what would it cost to replace it with something decent?: I do not know the kind of pump you are referring to. I will give my personal expertise. If it is a pump taking water from a tank, the piping might be loose, the knocking may be corrected with some air ventilation pipe. If it is pumping from a water tank: I suggest you look at a submersible pump capable of supplying water to 3rd floor. This kind of pump is less noisy. The noise at start, is the electric starter, and the noise at the end is when water returns and seals the stop valve. Also some air may be in the pipe, you need to purge the pump, as often as needed, try this first, and then the others. Good luck

Q: My radiator light came on this morning i was running late for work so i topped it off with water (about twice a year the light comes on, it has only ever had to be topped off) and after about 20 minutes of driving it started to heat up, so i pulled over shut it offsomebody stopped checked the temp of the water in the reservoir, said it felt to only be about 100 degrees, but topped it off with more water. the gauge dropped right back down to being almost as cold as when you first drive it, but after about 2 miles it was right back up near the red line.I pulled over again there was steam coming off the engine. I stuck my finger in the water it felt warm, but nowhere near hot. I couldn't get it cool enough to finish driving to work. Does this sound like the water pump?If so, how long should this take a decent mechanic to replace?If not, what else could it be?: sounds like u have air trapped somewhere or a flow problem water pump not pumping or thermostat not opening do not keep driving it b/c further costly damage can occur this shouldn't take more than a day for a good mechanic

Q: How to remotely control submersible pumps?: Yes, the pump remote control has been done by many manufacturers, and the program is very mature, Tangshan is one of them, you can consult yourself.

Q: guys i have a mini-water pump.....i wanna pump kerosene instead of water,to make a mini stove,on my own..my doubt is ...if the water pump is used to pump kerosene,will the kerosene ignite inside the pump itself or will cause any problem..i just want the pump to pump kerosene....will it ignite inside of the pump,because the pump runs on electricity....can u clear my doubt: Is the motor of the pump built-in so that the pumped fluid flows through the motor also? If the answer to the question is yes then do not use the pump for pumping kerosene. However, if the pumped liquid does not come in contact with motor then you can use the pump for pumping kerosene. But ensure that the pump shaft seal is of mechanical type (so that kerosene does not leak from the shaft sealing area) with parts (specially any rubber parts) compatible with hydrocarbons (use viton rubber parts instead of EPDM)

Q: I have two water well good water but not a lot of water .is it possible to hook two pumps up to one holding tank . if so how do I hook them up: it is very easy to do just email me. I'll send direction . I would say you have a small under ground stream of water . as you use the water from the well, it will take time to fill the well pipe again

Q: Because the water pressure is too small, this summer with self suction pump 750W, water is big, but every time that water is used for the first time out of the water is yellow like rust, probably after the release of 10 liters will become clear, then is not, but every one hour after the water time out is rusty hair yellow, so to waste a lot of water, but accidentally brought cooked food should not be good to the body.Now come in the water is through the pump, even without electricity, partition time for the first time water will be yellow, there is no master can teach me to disassemble, which can be cleaned?. Or something else. Thank you: If your pump is iron, it must be impossible to avoid rust, and if you replace it with stainless steel, there will be no problem.There is also a way to add a filter or water purifier at the front of the pump to make it a little better.You can change the flow parts into stainless steel, but the price may not be cheap

Q: What is the reason that the water supply of pump is getting smaller?: 1, the water pump screen plug, should remove the filter screen sundries.2, the use of lift is too high. Over the pump range, the pump should be adjusted to use height or replace the pump head.3, pump impeller plug or wear, should remove the impeller sundry. Replace the impeller if worn.4, pump outlet pipe blocked by debris, should remove the debris in the pipe outlet.5, diameter and pump does not match, replace the outlet pipe.6, the pump cover gap is too large, increased pump volume loss, should adjust the gap.7, pump body and pump cover leakage, should tighten the pump cover screw, make the pump body and pump cover close coordination.8, the pump speed is low, the use of voltage is too low. Should adjust the voltage to the rated value, replace the thicker cable or avoid peak use.9, water pump diving depth is too shallow, there is air intake, should adjust the diving depth. Pump running depth is not less than 0.5 meters.Yi Mai water pump to help you answer, I hope to help you

Q: Is it accurate to say that it should begin at 2, not at 0?: 0 degrees water turns into a mixture of ice water. Do you think the water pump will work properly?

Q: Im looking at putting a cabin on my property. I have a 200 gallon underground fresh water tank and i'm needing a pump to get the water into the cabin. i want to run a toilet, sink and possibly a shower. does anyone know the style of pump i would need that would only operate when i need it to that way it does not burn up.: I had a jet pump to run my whole house on my farm. It was placed in the basement, but it could be in a back room, too and they are pretty quiet these days. Does it freeze inside the cabin? I assume not. having it inside means if you have trouble even in freezing weather you can work on it in comfort. The end of the pie into your water tank will need a foot valve to keep the pipe filled so you don't have to prime the pump ( not a handy thing to have to do all the time). Other than that, the system is operated with electricity and a pressure switch which is settable. It will not run all the time this way. Not sure anymore but, for example the switch might be set to come on at 50PSI and shut off at 125PSI. You can tell by the switch or get a recommendation from the store where you buy it. (see pictures in link) Menard's sells these and department workers are trained to answer all your questions about installation, parts, and what you need,etc.

Q: Domestic pump does not use water, or turn, I do not know why?: The motor should be kept working, may be the motor switch problem, idling motor pump long time will certainly be bad, ha ha, the solution is to find a water pump maintenance master to work safety first!
