Question

how do i purge this , i have opened every faucet in the house, still next day there is a blast of air. HELP

i get the water from a well

Answer 1

Sound to me like additional air is getting in a closed system. Either your municipality has been performing work on the mains or air is entering your system from the house. I would look on the top of your new hot water heater and make sure the pop off pressure valve is not open, If its not I would contact the water municipality and ask them how air is getting in the system. If you had this work done 2 mos ago that is more than enough time to purge air out of the system.

good luck

Ok these people are not listening to you you are on a well, you get air everyday, you can purge it out but it comes back? If it were a foot valve you would have lost prime and had to restart pump. you need a new well tank and here's how to tell: you need an air compresser and an air pressure guage (tire guage) ok 1) shut off power to pump. 2) releive pressure on tank by opening faucets and allowing water to completely stop running 3)check pressure in well tank if you have a 30-50 switch you should have 25 lbs of air in the tank 40-60 35lbs 50-70 45 lbs if the pressure is incorrect fill tank with air until it is correct be sure and leave the faucet open while your doing this water is going to run out of the faucet as you fill the well tank with air 4) turn pump back on. you will hear the air leaking from the tank bladder OR next time you use your faucet you will have an overabundance of pressure followed by slow running water like your used to in that case check tank pressure again

Answer 3

The cold water inlet is probably hooked up as the hot water outlet. Every time you turn the water on you create an air pocket in the tank that has to be purged. If you look on the top of your water heater it will read in and out make sure the 'in' is connected to the cold water supply coming from the well or the street. OR if you have a well pump it could be an indication that your well needs to driven deeper. See if your pump then is running longer than normal. If all these check out, well you may just have the setting above 135 degrees. In the case of scalding hot water which really isn't safe for adults much less the kids. You're making hydrogen gas-that is the first thing to be expelled, you'll know-it will rattle the plumbing good.

Answer 4

THIS PERSON VERY WELL SAID,,, he gets his water from a well!!! so everyone of you is way off base!!! his problem has nothing to do with municipal anything,,,,,,,
you are getting air into your pipes,, probably from a leak in the tank area,,, and again probably the tank and somewheres on top of it,, if your pipes go up above the tank it could be there too!! usually you tank has enough pressure that it will blow water out of any leak,, so the problem has to be on the top of the tank, around that area or in a pipe where the water can run down thus letting air in!! another maybe ,, if your foot valve is sticking open it will let the water leak out into the ground and this will suck air in, when you turn it on again it has to blow the air out to get the water up!! if you can't find any leaks outside the tank area,, it is in the foot valve!! the valve may have just a little mud etc on it and the leak will be very slow,,, usually you can wash it out by letting the water run awhile,, like water the garden etc,,,,or it may need service

Answer 5

If you have run hot water recently in both of the sinks, the water will remain hot for some time until you clear the line of all the hot water. It all depends on pressure and length of line to run the water enough to clear it. I have to run my kitchen hot water for a full minute before I actually get the water from the water heater. As far as your problem; you need to A)have it serviced or B) have it changed out for new and if you have gas, get gas. Its worth it in the long run. Electricity is just going to go higher.

Answer 6

There is to much air getting in from your well. in many wells there is an automatic air injection system built into the top couple feet of the pipe. ther may be an automatic unloader valve connected about halfway down the side of the tank that is stuck or has become corroded so that it doesn't operate. repair or replace the valve. it is possible that when they shut down the water to replace the WH a chunk of junk got into it.

Answer 7

Depending on if you are on city water or a well, your pump could be pumping air if it is low... to purge your tank use the relief valve on your tank, but research on line how to do it or you will be scalded horribly. Good Luck!

Answer 8

To purge your water heater, there is a valve located on your water heater either near the top, or the bottom depending on what brand you have. be careful, water is scalding hot.

Answer 9

unplug water heater- shut off incoming water supply - to house- open faucets to drain-open valve on pressure tank, drain and refill.- open water supply.- plug in water heater- close faucets when water runs.----worked for me.

Answer 10

check the thermostat position, check the cold water intake line for the tank (may be partially closed !!!). Are you sure its from hot water line? Check the cold water lines as well.
