It may seem strange to think that there is a reason to avoid high water pressure in the home, but whilst low pressure can be a massive issue in terms of running your water based appliances, you will find that high pressure is actually really dangerous. Continual checks need to be made to ensure that the pressure in your home is at a safe level, or you stand to risk spending hundreds of pounds on repairs, as well as risking larger issues, like exploding boilers! The water pressure in your home will usually be dictated by the water supplier.
You will no doubt find that water suppliers need to regulate the pressure of their water supply in order to maintain their own needs. For instance, a pressure of around 100 psi may be needed to get the water from the pipes under the ground, up to the top of a tall block of flats, but the regular household only needs a water pressure of 80 psi. Some water supply lines will have pressure as high as 150 psi, which can be pretty dangerous. It is worth getting a gauge that can be fitted to a hose stop to test the pressure that you are receiving form your water supplier.
If you think it worth having a better understanding of it, and want to get to the bottom of any pressure related problems that you are having, then it may be worth getting a resettable tracking gauge, that records the range of pressure variations that you receive. This is incredibly useful if your leaks or ghostly flushes come at night, as the pressure that is delivered to your water supply can vary overnight, and a tracked gauge will show you when such things happen.
It is essential that you monitor and fix a pressure overload should you find one, as pressure building up in the plumbing can lead to serious damage to your whole plumbing system. If you think about the plumbing as a closed system, then you will no doubt understand that the weaker spots will be affected by too high an increase in pressure. This is obviously going to result in leaks throughout the house, which will seem unconnected, though they are all due to pressure issues. You may also find that the toilet flushes of it’s own accord, and that taps leak suddenly.
You can fix the pressure coming in to your home to a manageable psi by fitting a simple water pressure regulator. These mechanisms will ensure that the water coming in to your house is at a safe pressure, and will save you a lot of hassle in terms of damages and call outs to the plumber in mystery repairs! You should fit your pressure regulator at the meter, as then you will also be protecting the irrigation systems in use throughout the house.
Hot water systems are another cause of high pressure, as when water is heated, it expands, which leads to increased pressure in what we know is a mainly closed system. You will find that this pressure causes strange leaks in the same way that supplier pressure can. A thermal expansion tank is the answer to these issues, as it can accommodate the extra load of pressure applied by the heated water for when the hot water is running. Ensure that your home has these pressure prevention devices if you are concerned that your leaks may be down to such issues, and you should be well set to get fixed up and leak free!
Should you have a dry or slow blockage, where the basin is draining slowly, then there are other methods that you can apply. If you can’t be bothered to go out and get proper sink unblocked, you can make up a cocktail for unblocking the sink. Try pouring a table spoon of baking soda, a cup or so or boiling water and a decent few glugs of vinegar down there. You will see that the reaction is a fizzy, frothy one, that should bubble away at the blockage with a combination of carbonated action, acid and heat, which will speed up the reactions that the other two are using against the blockage. The hope is that the fizzing of the baking soda will whirl the acid in the vinegar around, as it breaks down the blockage. The pressure of the water sitting on top of it will push the blockage down, and you should find that the sink is cleared fairly easily. If not then it may be time to get the pipe cleaners out to see if there is something hard stuck in there.
