What does pool return do?
Similarly, you may ask, what does the pool return valve do?
In a pool plumbing system, there are pipes that bring water from the pool (suction pipes), and one or more pipes that take water back to the pool (return pipes). Pool valves are used to control the direction of water flow, to and from the pool, and in and out of equipment.
Likewise, is it worth it to put in a pool? A pool will increase the value of your home, but not enough to cover the cost of installing it. On average, it will increase the value of your home by 5%. So, if you have a $500,000 home, you can expect to get about $25,000 more when you sell it with a pool.
Also to know, how does a main drain work in a pool?
A pool's so-called main drain is not actually a drain; that is, it is not used to drain the pool. Instead, it is an outlet, housing a pipe that runs to the pump, which sucks water through a skimmer, then through a filter, then through a heater (if you have one), and then back to the pool via multiple inlets.
Do pools add value to a house?
In some areas, adding a pool may increase your annual property taxes, but it won't necessarily add to your home's selling price. For that reason, try to keep your total building cost between 10% and 15% of what you paid for your house, lest you invest too much in an amenity that won't pay you back.
