What Are the Main Toilet Parts & How to Properly Assemble Them?

A toilet is made up of several components that work together to enable its operation. Most of the intricate functional gears are hidden away in the tank which is like the engine of the toilet. It is important that you know the toilet parts and how to assemble them so that in a case of any malfunctions, you can know which parts aren’t performing. This post focuses on all the toilet parts you need to know in detail and how you can quickly assemble them. Join it to get information that could allow you construct a complete toilet without seeking help.

7 Easy Steps on Assembling the Main Toilet Parts

1. Prepare the Floor and the Soil Pipe

The soil pipe is the main line that connects the toilet to the sewer line. Therefore, before you start the assembly of toilet parts, stuff a piece of cloth in the soil pipe just tight enough to block the entry of sewer gas or to prevent hardware from falling into the pipe. Make sure that the hole drilled on the flow can accommodate the closet flange up to the collar. Fit the soil pipe while dry into the closet bend, then put the flange on top of the soil pipe. Establish the size of the gap from the bottom of the flange collar to the floor.To ensure a perfect fit, remove the soil pipe and trim it slightly using a handsaw to the distance established in the step mentioned above. You can also get rid of the burrs by scrapping the cut edge with a utility file. Finally, insert the flange to the soil pipe followed by placing the soil pipe in the closet bend. Make sure that the collar of the flange sits on the floor perfectly.

2. Fix the Soil Pipe Together with the Closet Pipe

At this stage of assembly, you will need a PVC primer which you apply in the interior of the closet bend and also on the exterior end of the soil pipe. Also, get PVC cement and apply it to the similar surfaces you used the primer and then fit the soil pipe into the closet bend firmly. You have to apply adhesive between the collar and the floor to set it in a proper position. However, make sure that the bolt slots align with the holes drilled on the floor before the cement dries up. Fasten the collar to the floor using long stainless screws into the subfloor.

3. Set the Stop Valve

In the assembly of toilet parts procedure, you need to keep the bathroom water supply shut. Make a hole into the main supply line using a tubing cutter in approximately 1 inch to provide room for the attachment of the stop valve plus the escutcheon. The pipe will have some water which you need to drain completely. Before you start soldering, remove the handle and stem of the valve since the heat can ruin them.Dry out the pipe both inside and out using a piece of cloth after cleaning it thoroughly. The interior of the inlet valve also needs scrubbing with a wire brush pipe cleaner after which you should season the surfaces with flux. While maintaining the valve outlet facing upwards, insert the escutcheon just above the supply line and then follow it by the stop valve. Heat the joint connecting the supply line and stop valve using a propane flame and then melt solder material around the joint until it gets full.

4. Place the Toilet Bowl

In the slots located on the flange collar, place the long brass closet bolts facing upwards and fit each bolt with a brass washer. Get an assembly wax ring and put it on the collar with the flat part facing down. Lower the toilet bowl into the bolts and press it down without rocking until its base touches the finishing floor. Add nylon washers in each bolt before nut-threading all of them first by hand followed by a wrench just tight enough not to let the bowl crack.

5. Set the Tank

When setting the tank, make sure that the wider rubber washer meant to sit between the reservoir, and the bowl is firm enough. Insert the smaller washers in the reservoir holes from within the tank when you are placing the bolts that will thread it to the bowl. Lower the tank gently onto the bowl guided by the shape of the holes at the back of the bowl where it is supposed to fit.

Nylon washers are necessary for the joints to avoid fastening porcelain over each other which may lead to cracking. Tighten the nuts alternating from one to the other until the tank is resting firmly on the bowl, and then connect the handle of the reservoir to the flapper chain.

In the tank, there are the fill valves, refill tubes, flush lever, overflow tube, float, and flapper all which come already assembled. If any problems occur, you can learn to fix them by searching some easy online tutorials.

6. Connect the Supply Line and the Seat Assembly

When connecting the supply line, fit it between the stop valve and the tank supply joint. After that, insert a plastic nut followed by a compression nut and a compression ring respectively onto the main line. In this assembly process, you will need Teflon paste in the valve outlet threads. Place the line in the outlet point after which you can insert the compression ring. Tighten the plastic ring with your hands followed by the compression nut using a wrench.

7. Place the Seat

Align the seat assembly over the bowl and fasten it with plastic bolts between the seat’s back and the bowl seat apertures. These nuts are fragile hence you should only use your hands to secure them. You can now turn on the water supply into the tank followed by letting free the stop valve. When the tank fills, perform six or more test flushes to check for any leakages.Those are some of the toilet parts and how they are assembled to make a fully functioning toilet. The procedure is quite easy as long as you have all the necessary tools and toilet parts mentioned in the post.
