RV Holding Tanks

RV holding tanks refer to two types of water tanks. The first holds what is called gray water which is the waste water that accumulates from the use of your sinks, shower and/or tub if you have one. This tank will never have human waste in it. There is a special tank for that as well. The second holding tank is for “black water”, the human waste from your RV toilet. All RVs  have different shape and size needs for holding tanks, some have more than three (more gray water tanks), but there will always be three, three tanks for your RV in total; the fresh water tank, the gray water tank, and the black water tank.

SPINWELD

Fittings Installation Service (Base Fee)

Regular price $121.00
/

If you're already purchasing an RV holding tank from us, chances are you will need the fittings installed specific to your application.  We have the tools and know how to custom spin-weld your fittings in place exactly where you need them.

Why use our custom tank welding process for your fittings?

• OEM Certified Application Process.
• Get your tank the same way it was installed the day you bought it.
• Permanent Leak Proof Process.
• Tank welding ensures no seam or void can develop at your fitting which is a traditional stress point.
• Simple For You.
• The tools and training to custom spin weld fittings onto a holding tank are expensive.
• Let our staff do it for you to get it right the first time.
Triple QC Check: Every tank we add spin welded fittings to undergoes a rigorous Triple Quality Control Test.
Impact Proof:  Your fittings will be tested for durability to ensure a permanent seal has been made.
Air Tight:  Air is thinner than water, so we pressure test your tank by injecting air and spraying a special soap like solution on the seams to look for seal voids.
Water Tight:  Once complete, we submerge your tank underwater and check for bubbles and leaks.

**PLEASE NOTE**
Once added to your order, you will need to email us a fittings installation schematic (picture / drawings) with exact location and measurements where you want them installed and which fittings in their locations.  Without this information your tank will be delayed. 

Email your schematic (picture/drawing) to help@elkhartrvparts.com or fax it to (574) 293-7004 - please include a cover sheet with ATTN: Elkhart RV Parts Spinwelding

This tank is manufactured for you when the order is placed. Returns are not accepted on special order products like this one. Elkhart Plastic tanks are manufactured to meet quality and health safety standards. With fewer impurities, these tanks are strong enough to take the bumps and bangs without compromising the security of your fresh water storage. Elkhart Plastics uses a process called roto-molding in which high-density plastic is rotated and molded into shape. This process creates a seamless tank in which the walls are of equal thickness, with no weak spots to cause trouble later. It is this process that has earned Elkhart Plastics the reputation for quality tanks. The dimensions of this tank are 38" in length, 37-1/2" in width and 8" in height with a wall thickness of 0.180”.
