Q:I'm going to buy a pump to take water from a lake and use it to water the grass at my cottage. I would like to run at least 2 hoses at the same time. I'm looking at one that's 3/4 horse. Is this too small? The yard is a little more than an acre.

A 3/4 horse pump usually has a one inch suction and 3/4 inch outlet and is more than enough to water one acre. Remember, you don't have to water every day or even cover the entire acre all in one day. The industrial/agricultural pump mentioned before (4 inch? 6 inch? Or more?) is intended for use on dozens of acres per day.

Q:I am looking for a small water pump that I can turn on and off using a computer, preferably via USB. If someone could please post a link or a method of me doing this myself, I will be very appreciative.

Well I am going to tell you the best site that I have found about USB I/O. Here we can get USB Lab digital Input and Output data acquisition interfaces series are available in many different configurations. They support a wide variety of industrial automation I/O control, test and measurement applications by USB. For more details visit the following link and enjoy ...

Q:I would like to ask the river for about 70 degrees on the steep slope pumping 170 meters, flat 40 meters into the pool, what should I choose water pump? How many heads? How to choose the water pump model? Thank you

70 degrees or so on the steep slope pumping 170 meters, vertical height of about 100m, you can choose the lift 120-150m of multi-stage pumps, nominal diameter 1 inches, 2 or 1 inches and a half can be.The power consumption of about 1520kW.

Q:A Honda timing belt is suppose to be replaced every 90,000 miles but is it necessary to replace the water pump at the same time? How long will a water pump last? I never had a water pump fail on any Honda I have owned. Of course that is probably because I always had it replaced with the timing belt?

Thats why you havent had one fail. have to remove pump anyway.

Q:how do you check the water pump? We started the engine with water running through the bunny ears and no water is running out.

Visually is the only way to check it. The water pump is located at the top of the lower unit. The lower unit has to come off to access the water pump. It's a fairly basic project for an enthusiastic DIYer with basic tools and a service manual. Once the L/U comes off, might as well install a new impeller, given the time effort to drop the L/U, not much sense re-installing a used one. first, remove the cowl and check the tell-tale outlet for a blockage.

Q:i have little leak from water pump need to replace it in my mazda 6 2006 v6 3.0l. i have little over 120.000 miles on it. Any body know how much it may cost me?

I don't know why, but the water pump costs between $125 and $160. That seems a little high. It probably retails for $186. Under normal conditions, you just get things out of the way, unbolt the old pump, clean it up and put the new one in. The problem is the other stuff that gets in the way. I'm just estimating the job will take 5-8 hours. Just multiply times the labor rate in your area. Don't forget the anti-freeze when you're done.

Q:Ok, so if i have an 80 watt solar panel and want to run a 12v dc fan and water pump ONLY when the sun is out or enough light to power them, will i need something like a voltage regulator? I would like to have the panels charge deep cycle 12 v batteries at the same time or when the fan and pump is not running. For instance, i have the panels out and my fan and pump on allowing them to run only on solar as well as charge the batteries. What diagram would i use? I would probably get a charge control for the batteries but more importantly what would i need to regulate the power from the panels? Inverter?

You may have to do some math. The 80 watt panel is only 80 watts at peak sun on a 75°F day at the equator. Chances are you will have something less than 80 watts to work with. But you can add up all the hours of partial sun to get an equivalant number of peak sun hours. An example would be a few hours in the morning and evening at partial power and a couple of hours at solar noon at nearly full power may give you 5 peak sun hours worth of light. 5 psh x 80 w/ps = 400 wh Your supply may have 400 watt hours worth of power per day. You state that the fan is 12v dc but what is the wattage? It could be a little 12v dc fan out of a computer or it could be a huge 12v dc fan out of an RV. What is the power requirements of the water pump? Is it a little 12v dc one for a foot tall decorative fountain or an industial 3 phase pump for a well? To charge the battery you need a voltage 120% higher than the battery voltage. 12v x120%=14.4 v To add up your loads convert them all the use to dc watt hours per day Here is an example to give you an idea of how to play with your numbers: Fan 12vdc x 1.5 A = 18 watts, use this for 5 hours your load would be 18w x 5hr = 90 watt hours Pump 120 vac x 2.5 amps = 300 watts (The AC will need to come from an inverter. The inverter has a certain amount of loss. How good it does the job of converting dc to ac is know as it's efficency. Lets use 90% to be safe) 300 watts / 0.90 = 333.4 watts, use this for 1/2 hour per day 333.4w x 0.5hr = 166.7 watt hours The 90 watt hours + the 167 watt hours = 257 watt hours per day. This would leave about 140 watt hours to put into the battery. Yes it would be best to use a charge controller to protect the battery from overcharging if the pump and fan are off, or from draining the battery too much if the fan or pump stays on.

Q:I have an 1982 El Camino 305 small block and am having troubles with determining if it is the gasket or the pump. I can't quite locate a leak, but it seems to centralize from the water pump and drip down the hose to the radiator. After my engine gets hot, which mind you my temp light has never turned on, and I shut of my car steam rolls out from behind my pump. I think it is the pump and please be it so. (Easier and cheaper fix. Replacement with a inexpensive part XP.)

Pull the oil dip stick if it has little bubbles on it and it is discolored you have a blown head gasket.Then pull your radiator cap when engine is cold, is it full or not? You can not trust what I call idiot lights because they usually come on after the damage is done.You can tell if the water pump is working by letting eng get to normal and grasp the top hose and squeeze it just a little,can you feel water running thru it,if not replace it.

Q:what could cause a impeller on a water pump to be completly shredded up i just had to change mine in my toyota camry and was wondering if i could do anything to prevent this from happening again?

I have seen this once before, the impeller was so old and corroded that it partially separated from the bearing or shaft on which it spins, and came into contact with the pump housing. No fault of yours, just replace the water pump with a new one.

Q:After I replaced the water pump impeller in my outboard I fired up the motor and now its not pumping any water through the pee-hole at all and also the prop is spinning in the neutral position (motor seems as if it is in gear and trying to move). Would this be because of the shift rod or the drive shaft not being in the proper position and possibly the impeller is being span the wrong in the impeller housing cup?

i am no expert on outboards. i did put an impeller on one with the same problem. no water output. seems there was a tube, that ran from the pump to the cylinder head. it was cracked, and the water couldnt reach the cylinder head. seems that the impeller shaft should always turn in the right direction, or it wouldnt cool in reverse, if you got this far , i am sure you will figure it out. you must be a pretty good mechanic to get that far,,
