The shape does not matter. This is fundamental to understanding hydraulic forces.
If you are talking about a hot water tank then the answer is no. If it is leaking from a fitting, it just needs to be tightened. If you can not tell where the leak is coming from, the water leak is the first sign that the tank is going to need replacing in the not to distance future.
Because compressing a gas increases its temperature. The increase in temperature increases the pressure further. By cooling the tank in water the tank can be filled with more air, it's also safer than having a very hot super high pressure tank at the end of the fill.
That depends on the weight of the fish as compared to the weight of the water their bodies displace. If it's a heavy, dense fish, then the tank with the fish would weigh more. If it's a light, less dense fish, then the tank with water only would weigh more. This assumes that the water displaced has been removed from the tank, right? If you are adding the fish to the water then I think it should increase the weight regardless of the density of your fish. The question then might be, does the fish weigh less when it is swimming than it would on a dry scale?
Constant gurggling is a sign of lime and calcium build up in your tank. If the bottom of your outer tank is very hot to touch you may need to replace the water heater. When this happens the lower part of the tank is very hot and as an example it is like filling a pot with rocks and water see how long it takes to boil on your stove that means you are using alot more gas to heat that water because it has to go through sheets of lime and calcium. I do not recommend draining and cleaning the tank because it is very expensive and who is to say that the control or tank will not last after that. You have to consider the age of the tank and your water system. Most of your heat is probably coming out of the front of the tank where the burner is at. I bet you have a dark brown spot at the front of your tank where the heat is coming out where you lite the pilot. There is alot to consider about a new tank, Most gas companies will give you a rebate for changing it out to a new one or have a program to replace your water heater by a contractor and they may(if you are in good standing with them as credit and payments go) add the cost to your bill monthly and you are not out of pocket any money up front and usually no interest. Call your gas company first. See what they will do for you. Good luck!
If the volume of the tank was effectivelly constant, and the tank was sealed to prevent gas escaping, the pressure of the gas would increase.
get a plummer to look at the problem
If it is coming from the tank: NO. If it coming from the bowl: YES!
Another tank will do nothing to increase the pressure. If it is city water, the pressure is regulated at themeter. The only thing that could increase it is to increase the size pipe supplying the fixtures. There is probably 3/4 inch coming into the house and it reduces to 1/2. The slight increase would probably not be worth the expense of doing. The pressure is still going to be the same, just more volume.
Increase the pressure to 40 PSI
To raise the PH of your water, you can run the water through a Neutralizing Filter which is a Tank similar to a Water Softener Tank with a Media called Calcite in it.
If you are coming from a city or county water main you do not need a water tank or pump system as the main should already be pressurized.
you cannot increase the pressure from a gravity tank by changing the pipe size, only the volume of water that will flow in a given period of time. The only way to increase the pressure is to increase the difference between the elevation of the tank and the elevation of the spigot. Many people will confuse an increase in water volume with an increase in water pressure, because, in both cases, more water will flow in a given period of time. ...moreincreasing the pipe size can reduce elevation loss due to friction which can translate in lay mans terms as an "increase in pressure"
If the water is coming from the main, it should not be dirty. If it comes from the cold water storage tank in the loft, maybe it needs to be cleaned or covered.
You cannot increase hot water pressure only. If this is low, your tank may need cleaning - You first turn OFF the power to tank, then attach a hose pipe to the bottom fitting, lead it outside or to any drain, turn on the valve by it, turn OFF your inlet valve and open the relief valve so air can enter the H/W tank.Let the whole tank empty -takes about 30 -40 minutes. Next, when empty turn ON the inlet valve and let cold water run through the tank and out the hose, now you will see the sludge coming out. Let this run 5-7 minutes or until water is coming through clean. Now you are done . Let it fill, then turn on power.
If you are getting water in the fuel filter, it is coming from your fuel tank. You will need to remove and clean the tank.
There is a shutoff valve on the cold pipe going into the H/W tank, if you close it no water will come out of the tank. There should also be a shutoff valve on the wall below each faucet/tap.
By elevating it higher as every foot higher will increase the static pressure almost a half a pound
