This guide will detail how to install fittings on an RV holding tank with an easy-to-follow method and eight (8) steps. An RV holding tank can refer to either the blackwater tank or the greywater tank. The blackwater tank, or simply black tank, is the container used to store human wastes that are flushed down the toilet in a recreational vehicle. The greywater tank, or gray tank, is used to collect water that drains from any on-board sinks or showers.<\/p>\n\n\n\n

Can be Used for RV Freshwater Tanks Also<\/h2>\n\n\n\n

While this how to guide focuses on blackwater tanks, the necessary tools and procedure can be used to install fittings on RV freshwater tanks also. This is so because the different tanks are made from the same material, polyethylene plastic. The tanks only differ in their intended use and exact fabrication. Blackwater and greywater tanks are non-potable grade tanks, while freshwater tanks are potable grade tanks.<\/p>\n\n\n\n

Why Replace an Old RV Holding Tank<\/h2>\n\n\n\n

Oftentimes, a new holding tank is needed to replace an old, well-used blackwater tank or to upgrade the storage capacity of an existing one. An old RV holding tank may need to be replaced when improper care has led to hard, nearly permanent sewage buildup, when a used rec vehicle is purchased and the owner wants to start with a fresh, clean system, or if the old tank has been damaged during movement or from chemicals. <\/p>\n\n\n\n

What is a Blank Tank<\/h2>\n\n\n\n

Most often, new RV holding tanks<\/a> for purchase are what are known as \u201cblank tanks.\u201d A blank tank is a storage container without any fittings or lids already installed. Blank tanks are just the container itself. The products are provided this way to allow the customer to install and set the fittings they need to match the water system on their personal recreation vehicle. Many times, an RV holding tank is a unique shape to fit under a rec vehicle, and many times also, the installation locations and even the size of the fittings necessary are unique to the RV system.<\/p>\n\n\n\n

8 Steps to Install Fittings on a Blank RV Tank<\/h2>\n\n\n\n

In short, to install new fittings on a blank RV tank the steps are to: order the correct replacement, get the needed tools, prep the tank, cut the holes, prepare the holes, install the fittings, and clean the now ready-to-use holding tank.<\/p>\n\n\n\n

Step 1: Order the Correct, Replacement RV Holding Tank<\/h3>\n\n\n\n

Ordering the right RV holding tank replacement is the first step. A replacement blackwater tank or greywater tank will have the correct volume storage capacity, tank shape, and size measurements for your personal recreational vehicle. <\/p>\n<\/div>\n\n\n\n

Finding the right specifications may require pulling out your RV’s owner\u2019s manual or getting underneath the RV. As the information may not be in the manual and the old holding tank must be removed anyway, this is likely the best option. With the old holding tank removed, the container can now be measured.<\/p>\n\n\n\n

Removing the old holding tank will also allow you to determine the size, number, and placement of the fittings that will be necessary. If the size of the old fitting is not labeled anywhere on the fitting body itself or on the connected plumbing, you can use a measuring tape and measure the fitting\u2019s inner diameter. The inner diameter is the fitting\u2019s \u201csize\u201d and can be used to purchase the correct replacements.<\/p>\n\n\n\n
