What are the best parts to repair a toilet? We interviewed three plumbers with a combined 39 years of experience to get their insights. Then we asked our parent readers for their do-it-yourself recommendations. Here are the ones we think are best.

Best Parts To Repair Toilets: Our Research

Let’s talk toilet repair!

Even the best made toilets will require repair from time to time. And given the high cost of having a plumber visit your house, it’s understandable why you might consider doing the simple jobs yourself. 

To get the best advice on which parts are best, we turned to the experts: three plumbers who’ve seen their fair share of toilet repair jobs. More than one told us that simple do-it-yourself repairs can be accomplished by even the most inexperienced homeowners (example: replacing a toilet flapper). 

One tip: have teflon tape ready if you are replacing a toilet fill valve. This tape acts like a sort of putty, filling in gaps between threads and making the repair more waterproof.

Here are the top toilet repair parts we would recommend from our research:

How We Pick Products To Recommend

We often turn to our readers (3 million strong!) to find products to recommend. We ask our parent readers for their favorites and consider their real-world experiences in our recommendations.

When we test a product, we always purchase it with our own monies. We do not take free samples, as we believe that compromises our independence.

We also fact check manufacturer information with our own measurements. If a maker claims a product weighs X pounds, we will weigh it to make sure. If the battery life is supposed to be six hours, we will see how it stands up in the real world.

In some cases, we will do interviews with experts in the field to get additional feedback on products.

To get hands-on time with products, we regularly meet one-on-one with gear companies and even tour manufacturing facilities. (When we do this, we pay our own travel expenses).

Why Trust Us

We’ve been rating and reviewing products for the home and families since 1994. We do extensive research, evaluating products with an eye toward quality, ease of use and affordability.

We make our living from affiliate commissions, but we always recommend what we think are the best bets for our readers (not the ones that are the most expensive). We are always looking for products that offer the best bang for the buck.

Our independence is a key reason why we have been doing this so long. As we mentioned above, when we purchase a product for hands-on testing, we do so with our own money.

Here’s another key point: we don’t take money from the brands we review. No free samples, no sponsors, no “partnerships.” Our work is 100% reader-supported!
