Q:Water pumps are always pumping water, what's the matter?: First check whether the water pump suction gas 2 check the negative pressure of the pump suction is too low 3 check whether the water pump 4 no problem of opening the pump head to check whether the water pump impeller damage

Q:In my house. Any ideas regarding how much this is going to cost me?: You need to get a second opinion from a knowledgeable friend or family member. When you say water pump , do you mean the well pump or is it a pump connected to the furnace that helps cycle hot water through radiators in the house? Please get a second opinion , maybe a friend or family can recommend someone who can help you.

Q:i need the location of the water pump or for the thermostat thank you: The water pump is timing belt driven and is under the plastic timing cover on passenger side. These water pumps have a history of breaking, due to the fact they have a plastic impeller and it shears off the shaft, which causes the engine to overheat. First you want to remove the thermostat and then check the water pump. Follow the lower radiator hose to where it connects to the engine. That flange is where the thermostat is at. After you remove the thermostat you can shine a light in the hole and put your finger in there, if the impellar of the water pump moves, it needs to be replaced. If it does, then you might as well replace the timing belt and tensioner, seeing how you have to remove it to get the water pump off.

Q:Plumber quotes installing system using cross-over valve which some way ties the recirculation through the cold water pipes. This sounds like a short-cut. Are there any disadvantages to this system?: what your plumber is installing is a pump and temperature sensor under a sink , hopefully the furtherest from the water heater. what it does is sense when the hot water temp drops below a certain point, at which time it pumps the water into the cold line until the temp rises again.. the obvious advantage being , not having to wait a long time at the faucet for the water to get hot.. the also obvious disadvantage being electric consumption.. not only for the pump and controller , but also with the water heater clicking on a little more often.. not a lot of expense but a balance against convenience..

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.: Sometimes I really wonder about Robert. Yeah, water boils at 212--AT ATMOSPHERIC pressure. But a cooling system is pressurized to RAISE the boiling point. So, ah, Robert is once again in left field. Because if you wait for it to boil over, you've probably already caused engine damage. You do NOT need a high volume pump. The 3 core radiator does NOT need more flow. The temp gauge should not fluctuate. That's the job of the T-stat--to regulate engine temp and keep it at a set point. If you're engine is getting hot at higher speeds, Check for missing baffles or cracked fan shroud

Q:I have a 1978 El Camino V8 305. My power steering has been going out on me, and since then my belt has been squeaking usually when it first starts up. This morning when I got to work, smoke was bellowing from under my hood. Im trying to troubleshoot. Is it possible that my power steering pump damaged the belt enough that the water pump went out?: If the power steering pump was dragging, you probably lost the belt, so the water pump was not working and the engine overheated. Water pump is probably OK. Replace the belt and fix or replace the power steering pump.

Q:I was was wondering how to calculate the head flow rate from a water pump. The water pump outputs 2 bar, which means that it will push water up to 20m in height. It also has a throughput of 2000 litres per hour.I want to pump water up to my loft, which is approx 15m above the pump.What will the flow rate be at this height? Is it a linear calculation of percentage of drop from maximum head height multiplied by the flow rate, (eg 5/20 * 2000 = 500 litres per hour?), or is it more complicated than that?: If your pump has more capacity than you need, you can always restrict the discharge and create extra artificial head.

Q:We came home one day to find our bathroom floor soaked, and we had no water at all.we later found out that it was the washing machine hose leaking.Our friend primed the pump but isent an expert..we fixed that problem with a new hose.A few weeks after, we started to notice that when you are in the shower, the water would shut off for a minute and come back on for a minute, so on so on, perfectly timed., and this got worse and worse, yesterday it would be on for like 20 secconds and off for 3 minutes... last night the water was working good but today we woke up with no water.The water taps in the house hardly do it at all. I also noticed that when we are running water the water pump goes crazy fast, i can hear it because its a mobile home.: If this is a well you are talking about, it may be a faulty pressure switch for a start from kicking on to often, and also it sounds as thou you don't have enough air in your tank not leaving enough air pressure so your pump kicks on too soon, and shuts off to soon. Check your pressure switch, and drain your tank completely, and see if that works. You will have some air at first, but it will stop in time. Your tank also needs to be in the right position as well keeping the right amount of air in it. Sounds like your pump motor still may be OK. One more thing, check to see if your check valve is shot.

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: DONT WASTE YOUR TIME. HAVE A PROFESSIONAL DRILL YOU 1 GOOD WELL.INSTALL A CONSTANT PRESSURE SYSTEM THEN YOU WILL BE HAPPY.

Q:I have a 1997 mazda 626 4cylinder. For a while now, my hot n cold gauge keeps wobbling back and forth. I was keeping water in it and it was fine. A week ago it went all the way to hot and started smoking. There is water gushing out right beside the pulleys. I'm not sure if it is the water pump or not. Now, my car won't crank. Someone told me that it was the rotor button, but i can't tell if it is bad. I don't really want to take it to a mechanic. Can someone help me?????: I am not a mechanic, but I can tell you that I just got my car back this morning from a mechanic because I had an almost identical problem. I had a slow fluid leak for a couple days, and steam would come out from under hood when I parked (after only driving for 10 minutes). Four days into this I went to the pharmacy and when I left I noticed I left a very rusty puddle of water in the parking lot. On the way home temp was running higher than normal. Let the car sit until a mechanic picked it up. Something happened with the timing belt and it caused problems with the water pump and coolant got in my oil. Had to have an oil change, coolant flush, water pump replaced, and a timing cover/gasket/seal something or other. $400 later I am up and running, good as new. Hope this helps and I hope you can find a good mechanic like I did.
