How to Install a Dual Flush Toilet

Dual flush toilets are smart appliances, designed to conserve water by having separate flushes for liquid and solid waste.. If you’re considering updating your home with dual-flush toilets, you may be wondering if you can install them yourself. Should you attempt to DIY or should you call a local plumber to handle the toilet installation instead? The actual installation process is almost identical to that of a regular toilet, but if you’ve never installed one of those either, you should consider the full process before making a decision.

Choose a Toilet

Picking out a new dual flush toilet may not seem like part of the installation, but there are many important considerations. Before shopping for a toilet, you should take measurements of the area where the toilet will go. Measure the distance between the wall behind your toilet and the bolts to make sure the new toilet will fit in the space. Then, check the size and shape of the base of your old toilet, and make sure the new toilet you pick out will completely cover that area. Otherwise, you will have unappealing marks around the base of your new toilet.

Remove the Old Toilet

As with most plumbing installs, the very first step is to shut off the water. Then, you must drain all the water by flushing the toilet repeatedly or using a wet-dry vacuum. Disconnect the toilet’s water supply hose, disconnect the tank from the bowl, remove the bolts attaching the toilet to the floor, and finally haul it out. Toilets are heavy so you may need help getting the old toilet out of the house. Using a dolly or wheelbarrow, when possible, makes the task much easier.

Install the New Toilet

Most new toilets will come with instructions from the manufacturer for the installation, so be sure to follow these exactly. However, there are a few steps most new dual flush toilets have in common. First, install the gasket of the new toilet. Next, install the offset collar/adapter. Put the toilet into place and attach the bolts to secure it. Then attach the tank to the bowl, connect the supply hose, and apply a silicone seal around the base of the toilet to prevent any leaks. Finally, you can reconnect the water line, attach the toilet seat, and your new toilet is ready to use.
