A high pitch noise after flushing is likely caused by the fill valve being clogged with debris. You can repair this and eliminate the noise by removing the fill valve from the tank, and then cleaning the valve screen. Place the clean fill valve back in the tank and flush as normal.

Yes, you can have a toilet without a septic tank. However, it will have to be a composting toilet. Composting toilets work similarly to aerobic septic systems in that the waste, which sits in a separate compartment below the toilet itself, is slowly broken down by aerobic bacteria. These toilets typically have a vent to get rid of harmful gasses with a fan, which requires a battery. You will have to dispose of waste in the toilet manually every three weeks to every three months, depending on how many people are using the toilet.

The biggest sign that your flange leaks is if you notice water at the base of the toilet. The cause is likely due to a poor flange installation, so you might have issues with loose bolts, an uneven flange, or a cracked plastic flange. Add a deteriorating wax seal to this, and you have a recipe for disaster. The best solution is to shut off the water valve, replace the toilet flange, and seal it with a new wax ring.

The order of your bathroom renovation should prevent damage to the completed work. Start with demolition and removing the old fixtures. Then, address structural repairs or water damage, if needed. Next, tackle the rough-in phase for plumbing and electrical work, install waterproofing, and work on wall treatments like tile or paint. Install your shower or bathtub, toilet, vanity, and sink. Flooring goes in after major fixtures but before the toilet. Lastly, install new lighting fixtures, mirrors, and other finishing touches as desired.
