How to Install Your Own Toilet – DIY Plumbers

Often times, one of the biggest problems that people face when taking on DIY plumbing projects is installing things by themselves, and by far one of the biggest fears so far is installing a toilet.

Towns such as Sunnyvale (and other Silicon Valley neighborhoods), for example, have some of the highest requests for plumbers to install things onto their plumbing systems.

On one hand, this is a good thing because of the fact that they are calling a professional that can guarantee his work, but on the other hand it is still an expensive job, and that is still money that could be saved if the job was done by the owner himself.

If you have more time than money, the do it yourself thing might not be a bad deal, but if you hate hassle, of course, you should consider outsourcing this stuff.

Luckily for us, toilets are not that big of a hassle to install these days, in fact the biggest thing that you will have to worry about is time more than anything else.

Despite it looking like a complicated and overwhelming task, the truth is that the toilet and the tank actually come with all the parts that you need in the kit. The only thing that you will have to bring to the table are the tools, and you will not need anything other than the standard plumbing tools that you can get for spare change at any local Sunnyvale hardware shop.

That is, of course, if you opt to buy a brand new one. If you opt to buy a second hand one, you will have to make sure that you get all the parts and source out the missing ones.


Hoping that the pipes and drains have already been placed into the bathroom wall where the toilet will be mounted, it is time to start the installation.

First you will want to start with the bowl and the mounting screws. These are the double-headed screws that you find in the little plastic bags that come with the toilet.

You drill a couple of holes in the floor where the toilet will sit, insert the screws in halfway then lock them into position either by using cement or good old fashioned elbow grease.

Then mount the toilet on top of the screws and bolt it into position.

Next up is the septic pipe. In order to connect the septic pipe to the toilet bowl, grab the wide flexible tube that came with the kit and insert one end into the back of the toilet bowl and the other in the opening in the septic pipe.

The next item on the list is the water tank. There are 2 ways in which you can mount it. Either low on the actual toilet or high up above your head.

Luckily they can go both ways so it is only a matter of preference here.

Make sure to bolt the tank on tight to the wall, regardless of the position that u chose for it and connect the water pipe to the side of the tank using a small metallic hose that is usually provided with the kit. You can buy a standard one at your local Sunnyvale hardware shop as well if need be.

Last but not least, now you need to mount the pipe that goes from the water tank and into the toilet bowl. It is a lot easier with a high tank and a lot harder with a low tank, however it is installable and the assembly itself is either 2 pipes that interconnect at the middle, or one single pipe that connects the 2.

Important notes to be made:

* You will be working with a lot of washers and rubber seals, so make sure that they are locked on nice and tight before installing them.

* Keep testing the system constantly for leaks and faults. If you do happen to find a leak or an installation fault, don’t try and patch it up, take out the entire part or section and reinstall it properly.

That being said, installing a toilet is a lot simpler these days than it was in the past, and even though it might look complicated or labor intensive, any Sunnyvale resident with a few tools and a basic understanding of pipes and connections can set one up and install it like a pro.
