What You Should Know Before Buying RV black water hoses


Quite a lot of RV hoses are made of materials that are not suited for transfering portable water like your drinking water and the water you use for cooking. When buying RV hoses that are needed for the use of drinking, washing or cooking, you should consider if they are labelled ”drinking water safe”. This means the hoses do not contain lead, bromine and other chemical materials that can contaminate potable water. Instead they contain UV-stabilized polyether-based polyurethane or polyurethane materials. You should also know that these hose that are drinking water safe are made to be easily identified by their colour. They always come in either white or blue colour. Also take note that hoses that are said to be lead-free may contain other poisonous chemical materials in polyvinyly chloride (PVC) like phthaletes, bromine and antimony. For RV sewer hoses, you can use any of these hoses without considering the materials it is made of, but it is good to get other colours aside from white and blue so you can differentiate your hoses and store them seperately.


The length used for an RV hose often depends on the distance of the RV from the dump station or the spigot. RV hoses are always manufactured in standard length. They are mostly 10-feet, 25-feet and 50-feet and a thickness of about 15 to 26 mils or 1/2 inch in diameter. The maximum length you can use for your RV sewer hose is usually 25-feet but your drinking water hose can be a long as 50-feet. If you need a hose as long as 50-feet, you can either get shorter hoses or get a single 50-feet long hose. The single long hose helps to reduce chances of leakages and also prevents water contamination due to less connections of the pipes. But a single long hose can also be difficult for you to clean and store in the RV when compared to using various short hoses connected together.


The price of RV water hoses usually varies from about 30 to 100 dollars. Heated RV water hoses are more expensive than the normal RV hoses. They prevent a bursting pipe when camping in areas that have a higher tendency of hitting the freezing point. Normal hoses freezes and get damage when they are in these areas of very low temperature. They are also referred to as insulated water hose because of their high insulating properties and are mostly blue in colour. This type of hose usually comes with an electrical device called heat strip. The heat strip is plugged alongside the hose into a valve and this help to heat the hose and prevent the water from freezing. The hose can also operate as a normal RV hose when the heat strip is not plugged. Lastly, the size and length of an RV hose determines how much it will cost. The longer in length hoses tend to be more expensive than the shorter ones.


RV hoses are compressible so they can be stored easily in the space provided in the RV bumper. Most RV do not have enough storage capacity for hoses that are as long as 50-feet and this make it difficult to store them compared to the shorter hoses. Alternatively, they can be folded and placed in a bin kept inside the RV. Alternatively, the 10-feet long hoses are able to be compressed to about 3-4 feet for easy storage. However, using multiple short 10 feet long hoses connected together can cause easy water leakages and pollution of the water flowing through it. The good side is that its always easy to sanitize connectable short hoses because you can always disconnect them to wash them inside and dry them out easily compared to the long hoses.


When cleaning your RV hose, its is always important to check the end of your RV hose when connecting it to the spigot for remainants of dirt particles. It is also advisable to sterilize your drinking water hose at least twice in a year. You can do this by soaking it in water that contains bleaching chemical agent for few minutes and rinsing it afterwards. After your camping trip, make sure you remove all the remaining water when disconnecting your hose to prevent algae, spirogyra and other bacteria that are easily attracted to water from getting into the hose and spreading inside it. Lastly, it is also advisable to cover the end of the hose with hose caps or a protective plastic cover after dismantling it. Note that longer RV hoses are more difficult to clean than shorter ones, so the cleaning approach explained above are more suitable and easier when you own shorter hoses.


In terms of additional accessories and add ons, having a water filter is important for your drinking water hose because it helps to remove impurities that creates unpleasant taste and odor in the water. You should also change and clean the water filter regularly as instructed by the producer or manufacturer so that you can use it effectively. Water pressure regulators are also needed to control the amount of water flowing into your RV. Excess water pressure can destroy your RV components while low water pressure makes it impossible to use the right quantity of water for any task you need to do like cookinr or bathing. A 90 degree elbow is also needed to easily connect your hose to your RV without straining the hose. They are mostly made of brass material because of their durability. Lastly, a quick connect which is usually made of brass is the instrument used to connect multiple hoses together easily. They are durable and made to be able to withstand high water pressure.
