How do I fix air in pipes that are causing them to make noise? I have tried to bleed the air out of them by turning off the water and opening the faucets but doesn't seem to completely work.

When Faucet is turned on I get a loud noise. If I use the Sprayer the noise goes away.

Sounds like water hammer. Air in the pipes. Lower volume of water out of the sprayer isn't enough to initiate the hammer. Try shutting the water off to the house and draining the pipes.
Open the offending faucet and turn the water back on this should eliminate the air in the pipes.

Cold water pipe noise

is there a knocking when you use the faucet or the pressure slams when you turn it off? that's water hammer. the air pockets that are supposed to be in the plumbing are depleted. most new plumbing have a length of pipe larger than the rest of the plumbing to hold air to avoid it. easiest way to fix this: turn off the water main. open up every faucet and flush every toilet until no more water flows. shut everything off again. slowly turn on the water main and the knocking and water hammer should disappear.

Hot water pipe clinging when closing valve

This could be a lot of possible fixes. Try putting a piece of tube insulation around the pipe at where it is hitting on a another pipe or something. This would at least stop the noise. That is the nature of the beast with the noise. Hot water responds that way depending on what is going on in the air .

99 sunfire loosing water and overheating

Lot's of these problems going around. First thing is to locate where the coolant is going. Is it leaking onto the ground or going through the engine and out the exhaust? As for no heat, Check to be sure you have enough antifreeze. Pure water can cause the engine to not warm up and result in no heat. Air in the system can also cause these problems and must be bled out through the air bleed screw on top of the engine. On most of these cars it is towards the passenger side front on a metal pipe. It's a funny looking fitting with a flat head screw on top and a hole on the side. With the system full and the car running, slowly open the screw until bubbles come out and continue to bleed until you get no more air out. Let the car run to reach normal running temp and try bleeding again and again until you can't get any air out (they're funny that way). If you can not locate coolant leaking onto the ground it's due to a blown head gasket or a cracked head.12_24_2012_5_56_58_pm.png

I Have a single handle peerless kitchen faucet that's making a shrill noise,and the water pressure is very weak.

Possible causes:
1. you have a air pocket t in the heated water system. You will need to bleed the system.
2. As to pressure, you may have knick in pipe somewhere due to worned plastic pipe.

When tap or cistern is filling loud noise from pipes

This could be one of two issues.

1. You may have high water pressure, causing the internals of the fill valve to vibrate and that vibration wave being transferred to your water pipes causing a reverberation noise called hammering.

An easy fix for this would be to reduce the flow to the fill assy. by turning down the units supply valve from wide open to about half way open. A few more permanent solutions may include, The installation of a Water hammer damper device - installation of a PRV pressure reducing valve - Although not intended for this issue is an air charged bladder style expansion tank installed, this device has been proven to reduce water hammering.

2. Water pipes that are not properly secured, loose and allowed to shake when there is a sudden surge of flow pressure. Much like a garden hose flexes when the nozzle is quickly turned on. This issue is most common with CPVC (plastic) water lines due to their flexibility and will require many more secure points.

A fix for this is a bit more labor intensive, due to having to access the un-exposed water lines in walls and ceilings so as to inspect and/or re-secure them to their surrounding structures.

A tip for securing the pipes where they penetrate through wall studs is to inject an expanding foam product in to the studs penetration, hence when the foam expands and cures it will form a very snug fit.

Note: if ether of these are the case, the problem should not be allowed to continue, because water pipe leaks could occur at the solder or welded connections and/or at locations where the pipes are rubbing against an abrasive surfaces causing a rupture.

Good luck
