I needed to cut a series of waste pipes and elbows first while also ensuring my waste pipe wasn't too steep. However, it's vital that you use a jubilee clip and screw it tight with a screwdriver. This ensures it doesn't come off. A pop-up sink stopper has 3 rods which help it to work as it does. The one connected to the drainpipe (and hooked to the actual stopper body) is called a pivot rod. The rod/strip with holes on it where the pivot rod is connected is called a clevis rod. 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

The reason our sink plugs wouldn’t hold water was because the rubber washer underneath needed to be replaced. You can pull apart the plug by untwisting the middle handle part, which allows you to replace the rubber washer underneath. This is the seal that allows the plug to stop water going down the drain. It didn’t matter how I contorted the washer, the plugs wouldn’t keep the water in. 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

The best products for sealing around sink

First, just for demonstration purposes, here's the bottom drain section. The pipe ideally should aim towards the overflow drain (as above). Something I learn since this picture, was to cut the overflow pipe down prevent from sitting on the bend and stagnating. 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 you decide to use silicone caulk, apply a bead of the same under the rim of the sink flange as well as around the sink drain opening. Carefully insert the flange through the drain opening and push it down strongly to get a strong seal.

The problem is i have a bit of a leak at this joint, even then the screw end is tightened as far as it will go the outside pipe can slide and move in/out (though to get it completely out would take a good pull). Scrape off old plumber’s putty or caulk from the top of the drain opening as well as under the rim of the flange. 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.If you clean the drain with water, make sure that your dry it completely. You can as well wipe it with a bit of rubbing alcohol.

The P-trap is the U-shaped part of your sink drain which looks like an inverted P. It holds a little amount of water at all times, preventing sewer gases from coming up to your house. Remove old sealant. Scrape it off with a putty knife or cutting tool. Make the job even easier with UniBond Silicone Sealant Remover.Here's a step by step guide on how I fitted the kitchen sink waste pipe and trap in my utility. It also includes a trap connected to a washing machine hose. Again, excess plumber’s putty or caulk will squeeze out from around the flange as a sign that you have a good seal. Scrap it off with a putty knife.
