How to Build a Gunite Swimming Pool, Part 3
Once you have the plumbing and electricity set up for your gunite swimming pool you are ready to begin the finishing steps of this job. You will find that the next few steps are ones that may be a lot of work, but they are completely necessary and will get you closer to your very own swimming pool.
Step 10 – Concrete
You are now ready to get the bottom of your excavated pool area shaped. In order to do this, you will need to pour the concrete in so that you can create a footer. You are going to need a lot of concrete for this task so having a truck come out to pour it is the best way to do it. Make sure that you get some friends to help you to smooth it out as it hardens. This is a large area and you will need to make sure that all parts of the hole get smoothed out as it is hardening. It is a good idea for the deep end to be poured first and then work your way to the shallow end and slowly make your way to the collar.
Step 11 – Filtration System
The filtration system is very important for your pool. In order to install it, you will begin by attaching it to the motor with nuts and bolts. The water line that comes from the pool needs to be attached to the side of the pump that is the suction side. Place a shut off valve on this side as well. From there, get a line attached to the outlet side of your pump. Your filter assembly needs to be connected to the discharge line with unions. Connect your back flush valve onto your discharge side so the filter can be cleaned. Get your shut off valve connected with a pipe going into your pool. You should use shut off valves on your discharge and intake side of your pump so that you can remove equipment easily.
Step 12 – Heater
You will need to install the heater now. Make sure that you get one that is going to be able to get a heater that is the right size for your pool. The heater needs to be about 3 feet away from your pool filter on level ground. Attach a segment of PVC pipe that is 1 1/4” to the inlet valve from the filter. You will now need to attach more PVC pipe to your return valve from the outlet valve. Secure all of the joints and pipes with plumbing compound.
Step 13 – Coping
You are now ready to install the pool coping. This will go on top of your pool panels. Get the bottom of your pool vacuumed out thoroughly before you begin. Get the pool liner unwrapped going along your pool, get it installed onto your coping. A professional vacuum will help to create a tight seal going around your liner. Coping on a warm day will make it smooth out easier.
