Q:New water pump leaking out of bolt hole?
my first response is, you used a wrong gasket or you mucked up the gasket when you installed it. Then i think of maybe the water pump casting cracked when you tightened the bolt. ( but not likely) . I guess you could try the sealer thing. but you could test it to see if it leaking from under the bolt head. The way you could do that is put a soft washer , like copper washer under the bolt head and put the bolt back in. the soft copper washer will make a water tight seal. if it were me , i would remove the pump and find out what the hay is wrong . i have replaced at least 6 water pumps on my own chevys, and have never had that problem.
Q:function of regulator in water pump?
This might be explained with an example. There is a water tank being used by a community (or a dwelling) and it is supplied by a pump from a well. There is a switch in the tank that is wired to the pump motor. The switch is activated by a lever attached to a float in the tank. When the float is in the down position the pump runs, When the float is pushed up by the water the punp is turned off. The pump first operates and fills the tank and then shuts off when the tank is full. When the usage of water drops the water in the tank to a certain level, the pump turns on until it is full again. The float, the switch and the motor are the pump regulating devices. This type of regulation is called two-position, like a light switch. Other more involved types of regulation may adjust a valve in the pipeline from the pump . This changes the rate of flow while the pump continues to run. The first type of regulation can be called digital because the flow is yes or no. The second can be called analog because while it is on, the flow varies in amount. If I have not adequately answered your question, maybe someone else will.

Q:my toilets are flushing dirty water and pump sounds not normal?
Oh, groan ...up at 5:30 in the morning with water problems! Well. I guess it makes life 'interesting! ...lol Your well is running dry. - It is what I suspect. - Had the same problem, long ago. First of all ...you don't have septic tank(s). - You have only (1) septic tank. You can't let your water pump run-on like that. - It will overheat and burn out. My water pump was $700.00 dollars! I'm suspecting your water recovery rate in your well is very slow. - Time of year 'possibly'. - Or your well was just not dug deep enough in the first place, to have much reserve water capacity. What looks like dirty water, is probably really actually only sand and silt, that your water pump is sucking up, when your well runs close to dry. There's a free remedy. Squeeze a clamp onto the rubber washing machine water hose. - To restrict the rapid flow of water into your washing machine. If you're watering your garden ...don't water for too long. - Or the well will run dry. I put a water timer on my garden hose, so it only watered my garden for 5 minutes, every half hour. Leaving it that way 'all night' and you'll wake up to a well watered garden in the morning! I'm sure this is your problem, - low water recovery rate in your well - because that would account for the water turning silty. Be ingenuitive ...and it won't cost a penny, or inconvenience. Trini ps. The water that is pumped into your toilet, is well water. The septic tank is where the well water flushes the poo poo to. pps. You're right in turning the water pump off while you wait for the well water to recover!
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:Well water house pump question.?
Okay, Adam, we also have a well and just put in a new one. The setting that says System means that the water is running through the filter. The setting that says by pass means that the water is NOT running through the filter. You will have water either way in your house (or you should). It is just either, it is running through the filter, or it is not. I hope I have helped. gram
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:how to replace water pump 97 pontiac bonneville?
It depends on which engine you have, with or without a supercharger. The non-supercharged engine is a piece of cake. the supercharged one is a bit of a pain to get at the water pump. On the non-supercharged engine, all you need to do is remove the serpentine belt, the water pump pulley and the bolts that hold the water pump to the front cover. I have detailed instructions if you send me your email address I can give them to you. They are from GM Service Information website. I can't give you the link to the website because I have to enter a password to enter the site through work.
