No doubt, each of us at least once in my life was a victim of pressure drops in the water supply network, when the shower in one second from the pleasantly warm becomes burning hot only because one of the family members turned on the washing machine or opened the tap in the kitchen. This rather unpleasant situation is not uncommon, if the water supply to the dwelling is mounted on a tee system. The situation is completely different when using special collectors for installing the water supply system. What is the collector of water supply and what does it need in the house - let's understand together.
Collector system of water supply
So, what is this - the collector of water supply in the house? Behind the formidable name lies a common splitter, dividing one stream of water into several (from 4 to 6). But unlike the tee, when the water is separated in the collector, the pressure in the system does not decrease. Support for constant pressure is achieved due to the fact that the inlet of the collector is significantly (by 20-40%) more output. The second plus of the positive side of the collector can be called the fact that with this installation at any time you can disconnect from the water supply each point of wiring, without overlapping the whole system as a whole. And this, you see, is very convenient. But in addition to the pluses of the collector system there are also tangible disadvantages. First, installing a water supply network using collectors will cost much more (approximately 8-10 times) - to connect each point you will need to build a separate pipe from the collector. Secondly, to accommodate the collector will need to allocate a separate place, which is unlikely to be found in the bathroom of a small apartment. Therefore, it is not appropriate to use such a system for supplying small apartments or houses. But for large cottages with many points of draw-off
Types of water supply manifolds
The material of manufacture distinguishes steel, brass, polypropylene and polyethylene collectors for water supply. All of them have a sufficiently high level of reliability, the service life of each is 40-50 years. By design collectors come with built-in valves and without them. When buying, it should be borne in mind that the manifold with valves, although easier to install, but somewhat less reliable. The fact is that the service life of the ball valve (valve) does not exceed 20 years. Therefore, to increase the reliability of the system, it makes sense to buy an unventilated collector.
