Q:does aquarium pump go in water?
It depends on what pump you have. If it is an air pump, no, it does not go in the water. If it is a submersible water pump, yes it does go in the water. Powerheads are one type of submersible water pumps. If it is an external or in-line water pump, no it does not go in the water. Most hang on back filters the pump does not go in the water, but Aqueon is one where it is designed to have the pump in the water. So, what pump/filter do you have?

Do it yourself and save $600. It's not that hard and it'll be a learning experience. If you have any friends that know how to work on cars ask them to help.
Q:Looking for help picking a water pump.?
I think you may want to look at the small pond pumps and just about any nursery or home supply store or landscaping store. they may have the specs on hand, or see if they can demo one for you. some places have a display pond set up already. You also might try a small swimming pool pump and put a voltage regulator in the line and adjust the pump speed that way. maybe rig a sewing machine pedal in the line and use a C clamp for an adjuster. I love rigging thing. It may not work with a gfi plug.
Q:Why can domestic pumps sometimes pump water and sometimes not?
You pump 1. is fully automatic, 2. have small pressure tank 3., stop valve should be 1., tap water is interrupted, 2. water intake, water out of harmony

Q:how to replace a water pump on a 1986 mercury topaz?
Just take off the fan belt, unbolt the water pump and fit the new one. Make sure the gasket area is clean and use a new gasket. If it has the fan on it, take that off first.
Q:Is water pump replacement necessary when it is working fine?
Water pumps have bearings, some new cars use plastic impellers. Eventually these do wear out. As you paid all the labor to get at the water pump, might as well replace it with a new one.
Q:radiator problems.....or a broken water pump?
I'd say the most likely thing is the thermostat. It is the most common cause of overheating when there is plenty of water in the system. As you already know, the radiator can leak and make it get hot. You can add water and it will stay cool for awhile, until the water leaks out again. The same can be true of a leaky water pump, heater core, or hose. If there is no leak, or no obvious leak, and the system seems to have enough water in it, but it still gets hot it is more than likely the thermostat. The thermostat blocks off the water from the radiator until the engine warms up. It can be damaged by getting too hot (like when you had a bad radiator) and fail soon after. Other possibilities are an electric cooling fan that isn't working, or a blown head gasket.
Q:can a failing water pump sound like rattling or popcorn until the motor begins to over heat?
Yes it can! I am curious though if what you are hearing is a really bad water pump or spark knock due to excessive heat or possibly a blown head gasket. Remove the belt and shake the pulley on the water pump. If it moves or rattles at all, then it is probably bad. Seems strange that it hasn't tossed the belt off though if it were that bad. Worth looking though, testing is free, parts are not....
Q:Ask the principle of fire truck and pump adapter
Fire trucks to bring their own water, when the water is insufficient, the municipal pipe network, water fast docking adapter or outdoor fire hydrant. These look at the specific conditions of the scene, usually take more outdoor fire hydrant, because the outdoor fire hydrant connecting the municipal pipe network, fire pool and other water sources, you can guarantee the reliability of water supply.
