Generally this is caused by pressure being built up from the water getting hot in the hot water heater. By code you should have a hot water heater expansion tank on the cold water inlet of the water heater to absorb the added pressure. If this is your problem, the excessive pressure could possibly burst your water heater. The faucet stem or cartridge or washer may be loose or moving and blocking flow.

Why would just the kitchen faucet sputter when first turned on and no others?

If this faucet has a spray hose, turn on the faucet and open the spray hose.This will adjust the diverter in the kitchen faucet to the spray and pressureize the hose.This will allow the faucet to equilize and the sputter will stop if the spray diverter is working. It could be that the diverter part in the faucet is defective.

What causes high water pressure in the first faucet on the water line from where it enters the house. The cold water is under high pressure but other faucets in house are fine.?

Possibly a pressure reducing valve installed after piping for first faucet, which would cause situation describing.

What could be wrong with a new bathtub faucet dispensing rusted water for the first 3 seconds when turned on?

I bet somewhere in the faucet the installer used a black iron nipple for the spout or shower head. The nipple rust very quickly. A few seconds of water rinses it out. The nipple will start leaking in the future.

Why does hot water come from the cold faucet and then change to cold?

Because hot water is still in the pipes from when you turned on the hot water, and when you turned on the cold faucet it had to let out the hot water first. This means you have a single-pipe sink. Double-pipe sinks have a pipe for hot and a pipe for cold and it blends them as it turns on.

Why is my Interior home water pressure low?

Old house, the pipes fill up with sediment. A 1/2 inch pipe may have a quarter of an inch or less. On some new houses there may be a pressure regulator on the line coming in. Somewhere between where it comes into the house and the first faucet or the water heater, whatever comes first. May just be rust and sediment at the faucet. Take the screen off the faucet and see if it is plugged.

Kitchen faucet does not turn on at first and after a few seconds it will start running?

Some faucets use the water pressure to open the seal after it has been released by the handle. It may be that the seal is tight and slow to move after it has been released. One other thing to check, is your water pressure ok at this faucet.

What is the first step required to fix a leaky faucet?

The most obvious step to fixing a leaky faucet is to turn off the water supply to the sink. That being said, another "first step" would be to know exactly what type of faucet is to be repaired.

Why is the water flowing into your Maytag real slow?

Water pressure, how far the valve is open on the faucet probably should be looked at first. If the hoses are old, you might check for leaks.

When I Had to shut off the cold and hot water now it is turned back on but doesn't work in all faucets?

Very often when the water is shut off and turned back on, mineral deposits come loose and plug the screen in the faucet spout. That's the first place to look. It may be in the faucet itself. If neither side works, look at the spout, if it is only one side, check the side that isn't working.

If altitude increases how does air pressure change?

The pressure drops with altitude. More quickly at first, but more gradually the higher you go. If plotted on a graph, you would get a curve.

Air in the water lines to the upstairs. Not enough water pressure.

Why would the water from your bathroom sink faucet but no other faucets taste dank when it is first turned on?

It's likely a rusted steel feed pipe and you don't use it often enough to keep the rust buildup flushed out.

No cold water only hot in moen faucet?

Why would the pressure in a bathroom faucet suddenly drop?

First place to check would be the airator screen on the faucet. The little screen where the water pours out of the screen could be plugged with iron or calcium depending on your water supply or plumbing material. The screen is just screwed in and should be able to be unscrewed by hand or gently with a pair of plyers.

When you turn on your kitchen fosset water will flow then stop then you shut it off and on before it will continue to flow None of the other fossets do this. Yes?

This isn't a Pond question, I moved it to Plumbing. But from what I have learned about plumbing from my many years of pondkeeping, you must have a restriction in your kitchen faucet line. Either the line is turned (partially) off with a valve (under the sink) or you have some kind of crud in the line that is preventing a free-flow of water; scale from old plumbing could do this. When you turn the kitchen faucet off it allows the water pressure from the house line to build back up on the faucet side of the restriction (e.g., between the valve, partially turned off, and the faucet itself.) When you turn the faucet on, this relatively small volume of pressurized water escapes from the faucet, but then it 'stops' since the restriction is blocking the free flow of water as in the rest of the pipes in the house. When you turn it off it allows a few moments to recover the pressure, then when you turn it on you get a spurt of water. And this is assuming the water pressure int he rest of the house is normal. * First look for the valve under the sink and be sure it is all the way on (in line with the pipe or turned all the way counter-clockwise, depending on the kind of valve and assuming it is installed correctly.) * Turn the water on full blast to see if the restriction is still there or will clear by itself. This could fix the problem right there. * If the valve is open and you still have this problem you better call a plumber. Depending on what kind of plumbing you have (copper, PVC, etc.), how far back in the piping the restriction is, and how much you want to learn about do-it-yourself plumbing, this could take a professional to find and fix the exact spot of the restriction. If you can trace the kitchen faucet piping line back to a juncture where it branches off to another line with a faucet that works, at least you will know in what length of the pipe the restriction is likely to be and how accessible it is. If it's anywhere in 20' of pipe and inside walls, this is probably not something you want to fix yourself. Good Fortune!

What makes water look cloudy when you first turn faucet on?

because it is cold

Do Igneous rocks change into sedimentary rocks?

yes, first they erode and the sediments are transported and deposited and then with time and pressure and heat they are turned into sedimentary rocks

How do you troubleshoot fluctuating pressure?

It could be as simple as air in the lines. First thing I would try is: Turn off the main water supply coming into the house. Then turn on all your taps while the water is turned off. Turn the water back on and start at the farthest faucet from the main and start turning taps off. Work your way back towards the main until you are done. Hope this helps.
