    Why should I use the low-flow toilet?

    Low-flow toilets have a powerful flush with minimum water usage. As a result, they help to conserve the environment and at the same time reduce your water bill. Also, most of the low-flow toilets are of a modern design which will give your bathroom an elegant appeal.

    What factors should I consider when picking the right low-flow toilet?

    Even if you want to save water, you also need to choose the right toilet as you don’t want to be uncomfortable. As a result, you should consider things like the type of toilet (one-piece or two-piece toilet), rough-in, flushing options (single flush, dual flush or pressure-assisted toilet), is it around a bowl or elongated bowl, and its maximum performance rating. All of these factors will help you to select a toilet that performs at a high level and is comfortable to use.

    Why does my toilet clog more often?

    A toilet can clog because of many things and some of the reasons include solid waste and tissue paper, balls, toys, cellphones, cap of the toothbrush, and much more. Always check your toilet and ensure that unwanted materials don’t go through it. If you’ve kids at home, you should constantly check your toilet for toys and other items that they may throw into it.

    Should I pick a dual flush or single flush toilet?

    Both of these flushing systems are very effective and clear waste very easily. But if your main aim is to save water, then you will be better off with the dual flush toilet. The dual flush toilet gives you the option of using either the partial or full flush, which helps you to save water in the end. This is not the same case with the single flush.
