Understand why the water in your house has no pressure and learn how you can solve this issue
(Sérgio Puchalski – Pressurization Specialist)
After a whole day in the rush, what we most want is to get home and be able to enjoy a nice bath so we can relax as we deserve. Too good huh? But when what happens is exactly the opposite and the water comes out of the shower without pressure, so weak that you have to “hunt for drips”… What a disappointment!
And it's not just in the shower that the lack of water pressure bothers you! It's in the hose to water the garden, in the faucet to wash the dishes or even in the water filter that takes forever to fill a bottle...
Yeah, the lack of water pressure is often a headache. Did you know that in more critical cases this can even lead to the burning of electric showers and water heaters? Dangerous and expensive, isn't it?
With that in mind, today we are going to explain some of the reasons that make this happen and, more importantly, give you some suggestions on how to solve this problem and guarantee you the comfort you deserve. Follow here with us and we'll help you!
For those who don't know, the hydraulic system is responsible for driving water through the pipes of a residence. The system consists of two lines, one for drinking water and the other that works only with the sewage system. It needs to be designed with great care to be efficient, especially towards the shower and toilet, outlets that consume the most pressure.
So the first question arises: how then to correctly design a hydraulic system to have good water pressure? Let's go:
First of all, it is necessary to ensure that the network has enough pressure to fill the water tank. That's right, the problem can be external, in the public supply network with poor pressure, which will make it very difficult for the water to reach the box as it should!
In these cases, it is very common that at certain times the water has greater pressure in the public network and sometimes there is not enough to fill the tank, causing a shortage. See how this issue is on the water meter, evaluating how fast the water tank is filling up. If identified that this is the problem, seek contact with the water company and request the placement of a system that increases the pressure in the network. If the negotiation is not successful, your alternative will be to design a system that includes a cistern. This secondary reservoir must be placed in a low place, to avoid filling problems due to the weak pressure to receive the water.
With the cistern, you can choose between two scenarios:
- Supply the cistern from the public network and the water tank from the cistern; or
- Supply the house directly from the cistern.
Under these conditions, to solve the problem of lack of water you will need to install a booster pump to transfer the water from the cistern to the water tank, or a pressurizer, or, depending on the situation, both. Of course, this will require some investment in equipment, materials and electricity consumption, but you will finally have that relaxing bath that you so deserve! It's investment with return on your well being, see?!
As for the water tank, we need to make it very clear that it is not its size that will guarantee that nice shower and adequate water pressure in the taps, but the height it is in relation to these exit points. This is precisely why it is common to place the water tank high up, on top of the house or in the attic, for example. It's like this: the higher you are, the more pressure you will have! If the height is not so good, the pressure will certainly be weak and in this case it is important to include a pressurizer in the project to help with the pressure of the entire system.
As for piping, the less curves the better! When plumbing is designed with many bends, bends and seams it is natural for the water to lose pressure. This is called system head loss and also needs to be considered.
Knowing the characteristics of the hydraulic system - how many showers and faucets will it serve, how high the outlet points are from the box, which "path" the water takes when circulating through the pipes and what flow you want to obtain, it's time to choose the suitable models of motor pump and/or pressurizer to compose the hydraulic system. Surely you already know, but, as they say, “it bears repeating”, FAMAC has the right product to meet your needs, whether with booster pumps or pressurizers.
And for those who love to combine comfort, economy and practicality, FAMAC presents the Esybox line pressurizers. Because they are constant pressurization systems, they increase or decrease the pumping speed according to the water consumption, thus keeping the set pressure always constant, generating water and energy savings. Compact, extremely silent, easy to program and install (just plug it in), Esybox pressurizers also have an International Potability Certificate, which ensures that the equipment does not change the smell, taste or color of the water. Are you going to say it's not amazing?
If, after evaluating all these questions, you are still having problems with the water going up to the tank or even reaching the water outlets in your residence, our suggestion is that you seek a technician specialized in hydraulic systems to help you.
