Q: i have a 1960 ford f100 and i was wondering if its better to have an electric water pump or mechanical. ive heard mechanical is worse because at low rpms it doesnt put as much water into the motor but i wasnt sure how true that was. What was is better so that my truck doesnt overheat? and how much better is one over the other if electric will just be a little better is it even worth using? also will i need to change anything on my motor to be able to put an electric water pump on it or will it just bolt on like the mechanical one does: Well your mechanical water pump is more than sufficient to pump water through your engine even at low rpms. Whether you have a electric or mechanical your can't pump more water though your engine than what your thermostat will allow you to. The advantage that i can see over electric would be the extra horse power you might get over having your mechanical

Q: need to know the electrical connections for a Square D water pump pressure switch..Have a quot;blacka quot;Redand the quot;ground quot;of course: The two source wires connect to L1 and L2. The two pump wires connect to T1 and T1. The grounds get grounded. When the pressure falls, the contacts pull together and connect L1 to T1, and L2 to T2, and start the pump.

Q: I was driving when my temp gauge shot up all the way so i pulled off the next exit and my car shut off and started smoking i noticed the water pump belt was in shreds and what seemed to be anti freeze fluid and water was everywhere. I'm curious what could have broke maybe a gasket or the waterpump it's self besides just the belt?: It seems to be a water pump failure, unfortunately that kind of failure is unpredictable and can easily sneak up on you. What happens is the pump fails and then the belt gets literally gets burnt off, this issue can be a cascade failure because the excessive engine heat can cause a number of COSTLY internal engine problems because aluminum engine blocks these days can't handle prolonged excessive heat. Hopefully not in your case, but just to give you an idea of the issue and everything surrounding it. The cost to repair at a shop can run anywhere from 200$ to 600$ depending on where you take it, you can do it yourself if you are mechanically inclined but i suggest a professional because they can also further detect any damage that the pump failure may have caused.

Q: Fire pump room is required to set up water pump control room?: What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control

Q: I was vacuuming up water from my basement I assumed was from the rain, suddenly water started spraying out of a blue pump at the base of my furnace, don't know what the pump does or why its spraying but its making an awful mess.: Furnace Water Pump

Q: i dont think that the water pump is out. i have a 88 evinrude outboard and the other day i noticed that the water was barley trickling out the hose. then it just stopped coming out the hose. it still comes out of the exhaust just fine. the motor is not get hot. is it ok if it still comes out the exhaust/ i will attemp to run a wire up in the hose to see if it is clogged later today. what do yous think: i use air pressure, but a piece of wire usually works.you may try to back flush it with a water hose.

Q: Why can't sprinkler system and hydrant system share water pump in fire fighting system?: Why not share mainly because the two impurities contained in the water system: fire hydrant system requirements of different impurities in the water spray system requirements loose, but more stringent requirements, therefore, the former can be welded steel pipe, the latter must use galvanized pipe, the purpose is to prevent rust plug flow indicator or end of the spray head.

Q: Do you need a stop valve for the pump at home?: Pump used at home do not take the water stop valve, the water level is too low, it can not pump up. In addition, there is no stop valve, not immediately pumping water, will have to wait a short time.The valve is actually a floating ball valve, when water is accumulated to a certain height, the float top, open the valve linkage; row water, reduce the water level, the valve is automatically closed, it realizes automatic drainage to steam pipeline.

Q: How do you check water pump on 98 deville haveing overhea?: You can't really check the water pump except that with the belt off, you wiggle it to look for play in the bearing. When the bearing gets loose, it causes seal failure and massive coolant loss. But after 100k miles it is time to do the pump anyway. Not that hard or expensive. Do the thermostat as well, just in case. But if no coolant loss, then overheating is probably from something else, like bad plug wire, intake manifold leak, plugged catalytic converter, retarded ignition, head gasket, etc. If the radiator was not clear, then the electric fan would go on often. Not likely radiator. Depends also on when heats up. If city driving, then likely to be fan or switch. If highway driving, then plugged convertor more likely. Put cooling system pressure tester on radiator cap. Check for leaks under higher than normal pressure. See if holds pressure. Then start engine and see if cylinder leak causes oscillation.
