I took it all to pieces before the house gets busy this morning and the rubber seals look fine (this pipework is only 6 months old so dont think anything has perished). If your P-trap is made of PVC, the connections will be hand tight hence no need to use a wrench. A metallic drainpipe with a metallic will need an adjustable wrench to loose. Note, don't rush this as you don't want to accidentally slip and scratch or dint your sink. Installing the Overflow Pipe for the Kitchen Sink Waste First, just for demonstration purposes, here's the bottom drain section. The pipe ideally should aim towards the overflow drain (as above). That is the only difference between the silicone caulk and plumber’s putty installation. Just like with the plumber’s putty, excess caulk will squeeze from around the flange. Wipe if off before it hardens. Testing the Seal

Scrape off old plumber’s putty or caulk from the top of the drain opening as well as under the rim of the flange.

Yes, you can continue to return items as normal as long as you follow the government guidelines about leaving your house. The reason you need to disconnect the P-trap is that it is always a good time to clean it as well. This is especially important if your sink is draining slowly as well. You can as well omit this step. If you put your plug in, and it still leaks, you may need a plumber to come out and replace the whole plug and waste. Scoop a generous amount of plumber’s putty and roll it between the palm of your hands into a long-pencil sized bead.

I recently cut a hole in my utility kitchen worktop as part of my latest YouTube series. However, after plumbing up my new tap, I then needed to learn how to install the kitchen sink waste and trap. Naturally, any sealant you use for sealing bathroom sinks or kitchen sinks must be waterproof and mould resistant. UniBond sanitary sealants are specially designed for use in the kitchen and bathroom; they create strong, flexible seals and offer long-term protection from mould. This means my washing machine waste and sink waste are hooked up and drain in the same place. Or, you could bore another hole through the wall, which I didn't want to do. How to Attach The Kitchen Sink Waste

Clean the area. Avoid exposing the surface to water. Spray a cloth or paper towel with household cleaner and clean the area. Wipe dry. Then clean again with bleach, before rinsing and leaving to dry.
