Q: We're doing some droplet impact experiments and are creating the flow of water to our droplet generators by elevating our source of water. Unfortunately as the water depletes the pressure changes. We need to siphon off the water from our lower basin where the water collects and pump it back up to the source (around 6-8 feet up). What kind of pump do I need for this?: I presume you can’t use city water! Droplets probably mean very small water flow. You can try local used merchandise store. Often they have waterpik systems for a few $ They are piston type pump that means the output will be pulsating instead of continuous. Another option is a windshield washer pump. These are gear type, so provide a continuous flow. You would need a variable power supply to control the pump speed, therefore the flow. Good luck Hope this answers your question

Q: just changed the water pump on my lower unit installed the lower unit and started motor now there is no water coming out of the upper flow tube is it becouse the engine is not warmed up yet or is something not lined up ...........: sorry but warming the engine will not affect the water flow. i had this problem i did not have the impeller installed properly.....took it to service center 3 hrs and $185 all new water pump kit fixed my problem . would have saved me alot of time and trouble if i had taken it in earlier

Q: I have a Miniworks EX Water filter with a ceramic filtering element. It has been used a few times without problem, but I am wondering at what point should I replace my ceramic filter? The replacements are $40 and I can't find any information regarding replacement times--only cleaning information. Does this filter need to be replaced often?I've always pumped from a clear river way up in the mountains and the flow is decent.: If the sparkling out is new, or notwithstanding if it somewhat is been wiped sparkling with cleansing soap, the sparkling out will pump out foamy soapy water. in simple terms maintain to pump water by it until eventually at last it somewhat is flowing sparkling and sparkling. shouldn't take greater effective than 15 pumps grant or take a pair of.

Q: no water is running my deep well pump kicks on every 15 min. it runs for 1-2 min when it kicks off then a noise like someone threw a ball against the house. can you help: check the back flow preventor sound like it might have trash and or build up casing it to stay in the closed position and when your pump turn off you hear that thud like sound due to the pump having to be slammed it reverse do to pressure build up.

Q: old sbc v8 water pump from oreilly's came apart and the fan ate up my serpentine belt, power steering pump pulley, clutch fan obviously, and put 5 holes in my new aluminum radiator. What will they cover? Remanufactured limited lifetime warranty. '78 chevy k10 350 sbc: there is only one way to recover your expenses and that's to put your vehicle in to a main garage for the repaires to be carried out, and ask them to make a report on what went wrong,with your report and detailed receipt send photocopy's to OReilly,s giving them the opportunity to reimburses you,on refusal make a free claim at the public small claims court and you will get payed out

Q: 2004 chevy impala 3.4 v6 The small leak is right behind the pulley of the water pump. Car is not overheating .the leak is only for a little while then it stops . water pump seems to be working fine but the leak ,what could it be ?: water pump seal is bad. it will get worse. just replace the water pump now and save yourself future problems. like losing all your water and over heating your engine. you need a new water pump.

Q: When the pump is connected in parallel, will the head and flow change?: Parallel pump should lift the same head, the flow is the sum of the flow of a single pump.

Q: do I need to replace it again ? How hard is it to change the water pump? Any Idea where on the internet I can download a free maintenance manual or replacement instructions ?: I would turn the crankshaft with the belt on until the timing marks line up, then remove the belt, do the work, then put it back together... if you take it apart with the timing marks out of alignment, then it will be more difficult to put back. just a tip.

Q: I would like a website that has pictures but any info would be helpful...: If its a 2003, you should still have a warranty on the powertrain unless its over 50,000 miles, or so. If indeed the water pump is leaking, you'd be foolish to leave it go; the timing belt can get wet, the belt and jump time and cause engine damage, that would be very expensive!! Save your self a lot of grief later by going ahead and replacing the water pump now; if you feel you're not up to the job, then have someone who knows VW's do it for you. Also replace the timing belt at the same time. An attempts to try and do a temporary measure will be met with an expensive result; a leaking water pump can also suck air into the cooling system and cause a hot spot, which could blow the headgasket, especially on a turbo model VW. Sorry, to tell you this, but its better to fix it now and save money, time, and pain later. I spent 25 years on/off in VW dealership service departments from 1980 till Dec of 2005. A car nut.

Q: HelloI am building a small budget underground room. On top of a very waterproof and airtight (besides vents) building, and running a dehumidifer inside, I would like to install a pump underneatth the foundation to suck out water from the soil surronding the building but I'm not sure what kind of pump would be best?Also how would b e the best way to set this up?: What you want is called a sump pump. Most have a system built into them that is triggered by rising water. The idea is to have a hole beneath that allows the inevitable water that will collect a place to go, then when a certain amount gets in the hole, the sump pump comes on and pumps it out to wherever you have the hose or pipes ran to. Being underground, good luck keeping the humidity level down. It won't be easy, and much depends on where your natural water table is, and what it is during rains. Someone in your area might know all that, I don't.
