Secondly, PVC pipe is easier to work with because its much easier to cut. You can invest in a PVC pipe cutter, but really, the hacksaw you have in your garage will do the job just as well.

Water Shut Off Valves

Water Shut off valves are the 2 oval-shaped or ring-shaped pieces underneath and at the back of the kitchen sink cabinet where the 2 water supply hoses are connected. They allow you the opportunity to turn off water to the sink and do repairs instead of turning off water to the whole house.

These valves can leak from time to time. The first thing you can do is to grab a wrench and tighten the compression nut and check if the leak stops.

If the leak persists it means that the washer is completely worn out and while you can replace the washer, getting a new valve is often the best option. These valves are in any case quite cheap.

Are kitchen sink drain holes a standard size?

This is a question that many people may ask, as there is no definitive answer. In general, kitchen sink drain holes are around two inches in diameter, but there can be some variation.

One reason for the variation in size may be due to the type of sink. If the sink is apron front or farmhouse style, the drain hole may be larger, as this type of sink is typically larger overall. Another factor that may influence the size of the drain hole is the material from which the sink is made. A sink made from heavier materials, such as cast iron, may have a larger drain hole than a sink made from a lighter material, like plastic.

If you are unsure of the size of your kitchen sinks drain hole, you can measure it easily. Simply use a ruler to measure the diameter of the hole. If you are not able to measure it yourself, you may be able to find the size listed on the sinks packaging or on the manufacturers website.

If you need to purchase a sink drain that is a different size than the one that came with your sink, there are a few things to keep in mind. First, make sure that the drain you select is compatible with the type of sink that you have. Also, be sure to measure the size of your sinks drain hole to ensure that you select a drain that will fit.

  • What Are The Parts Of A Kitchen Sink Drain

    A kitchen sink receives water from the cold and hot water pipes and after the water is used for cleaning purposes it drains out from the bottom of the sink. For this to happen, several parts need to be assembled together and work seamlessly.

    Old kitchen sink drainpipes were made of iron or steel, but they are hardly used in modern plumbing. The ideal material for kitchen sink drainpipes is copper, polyvinyl chloride , and acrylonitrile butadiene styrene .

    PVC and ABS drainpipes are cheap, easy to install, corrosion resistant, have smooth bores which means high water flow rates and therefore less clogging, leak-free joints and are long-lasting. Copper drainpipes are expensive to install but are quite attractive.

    All kitchen sink drains/wastes are of the same size. The standard kitchen sink drain size is 3 ½ inches. If you need to replace a kitchen sink strainer you dont have to measure the size of your kitchen sink drain opening.

    Although your kitchen has a separate drainpipe, it is connected to the main house drainpipe together with other bathroom drainpipes . The main house drainpipe then drains the waste out to the citys sewer pipes or in the septic tank.

    This means that all of your fixtures drainpipes are in communication. If for instance the vent is blocked and air cannot flow in and out of the plumbing system, you might hear your kitchen sink gurgling when the toilet is flushed or when the bathtub drains.

    What Are Sink Strainers Made Of

    How To Install Kitchen Sink Drain Strainer, Stop Leaks

    Just as there are many types of sink strainers, there are also a variety of materials they will usually come in. A large number of sink strainers will usually be made of stainless steel for corrosion resistance due to the unlimited exposure to water and other liquids. There are also other sink strainers that are made of silicone, rubber, and even plastics.

    Each of the materials used to make sink strainers also has unique properties that help to make a particular sink strainer very useful for special purposes.

    Stainless steel is the most common material used for sink strainers because it offers high durability and sturdiness unlike any other material used for sink strainers.

    Sink strainers made from stainless steel can withstand hot boiling water and extremely cold or freezing water. The best part is stainless steel sink strainers are also rust-proof which essentially when you think about it is one quality you would want your sink strainer to have.

    As mentioned before, there are other sink strainers that are also made from silicone. Silicon is a material that is highly resilient just like stainless steel.

    The best thing about sink strainers made from silicon materials is that on top of it being able to withstand extreme hot and cold, it has an added advantage of flexibility quality sink strainers made from stainless steel lacks.

    Personally, rubber is always a big no because I would always want the best out of my sink.

They are also less likely to cause damage to porcelain or metal sinks during installation or cleaning.

    If you prefer stainless steel sink strainers but are concerned about sink damage, consider sink strainers with built-in sink protectors. This feature is usually made of silicone, and its main purpose is to keep stainless steel strainers from scratching sinks.
