Often it happens to design the furniture of the kitchen when the drains and the electrical outlets are realized.
The furnishing project therefore adapts to an already defined environment and it can happen to resort to expensive oversized elements to obtain a furniture that meets the real needs.
This is because in most cases the placement of drains and electrical sockets does not follow a precise project, but takes place on indications hastily supplied to the building site without a real design awareness.
The correct procedure would instead design simultaneously the kitchen furniture and equipment .
In this article I would like to focus on the hydraulic system , analyzing some technical issues to keep in mind when designing a kitchen.
Plumbing in a kitchen against a wall
Of fundamental importance in the design of a kitchen is the position of the sink . If the kitchen is placed against a wall, the pipe outlets for water supply and drainage should preferably be made at the sink base, which is the only one that can be inspected.
empty sanitary kitchenIf we really can’t place the sink and water outlets in the same spot in the room, we can resort to the so-called sanitary void (or equipped channel), which many kitchen manufacturers have been offering for some time.
In fact, the furniture bases have an empty space in the back towards the wall, with a depth varying from 6 to 20 cm, in which the systems can be passed.
We see it well in this drawing that I found on a Snaidero technical sheet and on which I indicated the element that interests us.
If we decide to exploit the sanitary vacuum, it is preferable to install the drain pipe at a lower level than the water supply pipe to avoid interference in the event of leaks.
However, I would consider this option as an extreme case, since it eliminates the possibility of inspecting the system, which is very convenient when the sink and outlets are located at the same point.
Instead, I prefer to use the channel equipped for water pipes that concern some kitchen appliances, such as the dishwasher, to convey their drains into the sink.
height from the floor to drain the kitchenIn addition to the position of the sink connections in plan, it is necessary to think about their height from the ground .
The height depends exclusively on the kitchen model we choose. The sink furniture has an opening in the back, inside which the attacks are placed.
If we choose a kitchen model that rests on the floor and with a plinth, generally there are no particular problems due to the height in which to place the drains on the wall.
It is different if we choose a model that always rests on the ground but without a plinth and with visible legs, or a suspended model.
In this case it will be necessary to check the height of the drains so that they do not come out underneath the furniture.
