Q: I just noticed a slight leak from my water pump. About the size of my fist. I called one mechanic and was told the 2001 BMW Z3's water pump seals are tight and do not leak with the car is running (engine is hot) but once the car cools the water pump seals expand resulting in the small leak, that I shouldn't worry about it unless it leaks more, the engine over-heats, or dash light turns on. The BMW said I should have the water pump replaced but he may have just said that to make a repair sale. Anyone out there know the truth?: Some seepage through the bearing seal is normal for new pumps. I've never had it happen to me, but that is what I read in the information sheet that the pump came with. If it's leaking out of the gasket area, then you will need to put on a new seal. If the new seal doesn't have anything on it to help the gasket seal such a Felpro's printoseal, use RTV sealant on it and allow it to cure before driving. It is sticky and messy, but it works great.

Q: Can I install a recirculating hot water pump to a boiler? Someone just told me that I have a boiler not a water heater, but I have to wait for minutes for the shower to heat up: I merely positioned one in my homestead and did no longer use a pump. Mine is precisely gravity. I decrease into (with a tee setting up) the present warm water feed line at a factor which became farthest from the water heater and then deliver a clean line back to and teed into the drain on the very backside of the heater. I positioned a diverse off valve interior the line merely up from the hot tee close to the drain so it quite is adjusted or close off if mandatory. (Mine is open and has been considering I put in it) some structures could require a verify valve interior the hot return line on the horizontal area of the return line close to the water heater. I positioned one in in spite of the fact that it does no longer enable my equipment to artwork so I bumped off it and all is definitely now. All you're doing is making a loop so the nice and comfortable water is often circulating from the heater by way of the feed lines and while it cools slightly it returns by potential of gravity to the tank. this is the very ultimate subject I even have accomplished in some years. this gives you instantaneous warm water and no pumps, no electric use. you may learn this equipment on the internet. merely Google for it. solid success

Q: How much would it be in labor and parts to change a water pump and on a 2000 Dodge Durango 5.9 4 wd with 109k.miles? Should I change the timing chain? If you can please give me a estimated Thank You!I getting tired of old Vechiles LOL: The cheapo water pump from oreillys is $46, the higher end one is around $70. As far as labor, Mitchell OnDemand calls for 2 hours flag rate time to change it out. You'll probably be looking at at least 1 gallon of antifreeze as well for what will be lost changing it out, and I would recommend changing the thermostat when you change the water pump. The 5.9 uses a timing chain, which I wouldnt recommend replacing, seeing as the vehicle has that low of miles on it. I'm not sure how much labor costs in your area, but the shop I work at charges $75 per flag rate hour. So if we were to do it, taxes and everything it would be right around $250. If you live in a big city, you'll probably be expecting to pay around $100 a hour for labor at a reputable shop. Good luck and hope this helps.

Q: I have a 1969 Chrysler with a new 3 core radiator. It still has the stock water pump and I am wondering if a high volume pump would make it run cooler at higher speeds. It runs hotter when you get off the freeway. I have flushed the system and installed a new thermostat. I also replaced the fan clutch. I am at a loss of why it still runs warmer than the 180* thermostat.: High Volume Water Pump

Q: How much is the flow rate of fire hydrant and spray shared water pump?: Fire fire water is superimposed, at the minimum, the lowest 5L/S automatic spraying fire hydrant, light danger level 13.9L/S, the least is 18.9L/S, but the data is useless, the data are not spraying fire hydrant, concrete analysis of high-rise buildings like the dangerous level according to the calculation, the general design, the concrete building needs the high-rise building minimum 20L/S, automatic spraying dangerous level according to the general 30L/S, 50L/S need to flow

Q: Theirs a house on a hill and a pond at the bottom of the hill what kind of pump can pull water 50ft up a hill?: you could not, if that fifty feet is the vertical height. the optimal height a pump can suck water up is approximately 32 feet. that's constrained via the atmospheric tension and might't get replaced. One option is a pump on the backside interior the pond, pushing the water upwards. yet another is a jet pump, that may take a seat on the appropriate of the hill. It sends a jet of intense tension water all the way down to the pond, and that jet there pushes the water upwards. This must be primed, although. IF the 50 feet is in basic terms the slope distance up the hill, calculate or degree the vertical height, that's all that counts. .

Q: My water stopped working and my tank emptied. I replaced the pressure switch and the gauge. It still didn't work. The well is about 110'. I pulled the pump and replaced it (1/2 HP, 10 gpm, 2-wire). It still doesn't work. The old pump was 15 years old. The one before only lasted 7 years. The water has a lot of sediment. I have never done this before, but it seemed straightforward enough. The wires on the pump were not differentiated in any way (same color). Could I have put the wires together incorrectly? Could I have put the switch in wrong? It doesn't click on when the breaker is turned on. What else could be wrong? Could the breaker be bad? It wasn't kicked out.: Sounds like the vertical check valve between the end of the pump line and the pressure tank is bad and allowing the water to go back down the pipe when the pump isn't running. Papaw

Q: What is the relationship between pump power, lift and flow?: When the power is constant, the kinetic energy theorem is known as P=F*V, that is, W=F*S.In the water pump, it is said that the work done by the unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.

Q: We've changed the hoses, and thermostat for the radiator. It still leaks coolant but we can't find out where it's leaking from.: 1999 Honda Accord Water Pump

Q: When the pump is running with frequency conversion, the instantaneous power is greater than the power frequency operation, and the actual flow and lift are less than the power frequency. When running, the efficiency is very low. Why?: There is a running curve for the fan and water pump.Enough is enough
