The P Trap Buyers Guide

The P Trap was developed as part of the drainage system for the plumbing in your home or business. The P trap will also stop sewer odors from coming back up the drain and into your bathroom. This trap has been used all of the world for many years and will continue to be.The p-trap is found in the bathroom, the kitchen, the basement, the bar and many other places in your home.Many P-trap's can also be found in many commercial places of business. P-Traps can be found in fast food places, supermarkets, schools,hospitals, zoos, office buildings, outdoor showers at the beach and pretty much every where you can find a fixture drain. The P-trap can be found under most fixtures. Common places you will be able to see the p-trap are under both your kitchen and bathroom sink. If you have an laundry tub/sink you will be able to see the p-trap under that as well. Your shower and bathtub also use a p trap but you will or will not be able to see the actual trap. This will depend if you have a basement, crawl space or even live on a slab. If your bathroom is built on a slap you will not be able to see your p trap because it will be "inside of the slab", which is under the bathtub or the shower pan. If you have a bathroom that is built on the first floor and you have a crawl space or a basement you will be able to see your p-trap if you go into one of those areas. The only problem you may run into is if your basement is finished, you may have to remove some Sheetrock from the basement ceiling before you can access the p-trap and the bathtub trip lever or shower pan drain.

Different Styles Of The P Trap:

If you need to install a new fixture or possibly replace an existing p-trap, you will need to know that there is a difference when it comes to buying a p-trap. There are two different mechanical styles of the p-trap as well as a few choices of material that some p traps are made from. For example, P-traps are made from PVC, Brass, Steel, and sometimes even a rubber replacement can be found in places like Home Depot, Lowes, or a local hardware store. Depending on where, and what type of fixture you are installing or repairing will determine what type of p-trap you will need to replace. In most cases the local plumbing code will tell you what type of trap should be used in the area you are working in. These plumbing codes will also vary from state to state. So if you know a professional plumber in another state and they tell you what they use it may not be what your state requires. It is also very important to remember that just because a certain type of p-trap is install, that doesn't mean that type is supposed to be there. In fact when many people "ticker" with there plumbing they just grab the first thing that fits and works and it gets left, they sell the house and someone else moves in, they experience problems with the trap not because its the trap, but it very well could be because of the wrong trap that was used. This is why it is very important to replace your p-trap with the proper type and style.

The PVC P Trap:

The PVC P-trap can be found in many newer homes as well as many commercial buildings. There are some advantages to the PVC P-trap like less corrosion and longer life of the p-trap fitting in the right environments. The PVC P-Trap comes in many sizes and a few different styles. The most common sizes of the p-traps that are used in homes are 1.5" and 2" traps. Most states require the washing machine, or the washing machine p-trap to be at least 2" inches in size for proper draining. Most states will also require something called a "soap stack" as well that should be glued to the p-trap. If you go into the bathroom and look under your bathroom faucet you will see the common 1.5" P-trap, now walk into the kitchen and you will find another 1.5" or 2" p-trap depending on your states or local county's plumbing code. There are two different types of PVC P-Traps to choose from when you are ready to repair or replace your trap. The names of the two different types of p traps are the "swing joint p trap" and the "glue p trap". Both kinds of these p-traps let the water flow the same way but they are different when it comes to installing them. The first type of p-trap we will talk about is the "swing joint p-trap". This type of p-trap is very standard in many plumbing installations because of it's ability to be serviced after installed, and in fact in most areas, the swing joint p-trap is required by the plumbing code. The swing joint p trap which is sometimes if referred to as the tubular p trap has nuts and washers where the two parts of the trap connect to each other allowing the trap to "swing" from side to side. This is handy when installing a new sink or replacing an existing p trap. The second type of p-trap is called the "glue p trap". The glue trap is exactly what it sounds like. It is a PVC p-trap that gets assembled and installed with glue. This type of trap is more commonly used in area where there will be no access to the trap such as shower pans and tubs that are roughed on the slabs. Unlike the swing joint or tubular p trap, this type of trap is permanently in place once the glue is applied and can not be taken apart if the trap need to be serviced.

The Rough & Polished Brass P Trap:

Besides the PVC p-trap there are of course other things that a p-trap can be made from. Another common material used is brass. Brass comes in two different types of styles when it comes to plumbing and p-traps. There are "rough brass p-traps" and there are also "polished brass p-traps". There is a major difference however between these two types of traps and coatings. The Rough Brass P Trap is exactly what is sounds like. Its a rough unfinished brass that is dull and boring but every effective in areas where the trap is not to be seen or noticed. This type of trap is often used in commercial bathrooms and sometimes even bathrooms in the ordinary home if there is a vanity. The Polished Brass P Trap is something a bit nicer then the standard rough brass p trap. The "polished brass p-trap" is nice and shiny and polished to look as if it was chrome. This type and style of p-trap is often used in areas where the p-trap is fully visible, for example a pedestal sink. The polished brass p trap is also more expensive then the standard rough brass trap. When you also start working with polished brass materials you need to be very careful when using tools so you do not scratch or chip the polished finish.

How To Install The P Trap:

1) Take the trap arm and stick the non curved end into the trap adapt sticking out of the wall. You might have to loosen the trap adapt and make sure that the feral is also in line or you will not be able to get the trap arm in. 2) Once the trap arm is installed inside the trap adapt you can now hook on the U part(the trap) of your trap by tightening the nut on the trap arm to the U joint. 3) You should now have the trap arm in the wall and the U joint or the trap as its called assembled. Once you have both of those done you now should hook your drain tail piece into the top of the trap. 4) Now that all of the parts of the p-trap are connect you will want to make sure that all of the "trap nuts" or the nuts on the p trap are all tight. If your p trap is made from PVC you will want to be careful and not over tighten the trap nuts or they can strip or break. If you have a brass or tubular p trap you will want to make sure the trap nuts are tight and might even want to use some pipe dope or Rector Seal on the threads and the p trap washers. If you are tightening the Polished Brass type of p trap you will want to be extra careful that you do not scratch or chip the finish. 5) Once all of the P-Trap is connected and tighten you will want to fill the sink or the fixture up all the way and check for leaks. If you see no leaks then you have done a good job. If you have read this and feel that it is something that you can not do, then you should call a licensed plumber to repair or replace the p-trap for you.
