Changing Out a Valve on a Water Tank

[Two Plumbers in Overalls]

Do you find yourself frustrated with a leaky valve now that your rainwater tank is full of water? Do you feel bad about “wasting” the water that will inevitably be lost to this error?

How much time have you spent worrying about the planning, time and resources it will take to fix this mistake?

If the answer is more time than I would like, then today’s video is for you. I am covering how to quickly and easily switch out the valve with no big water transfer pumps or complicated Rube Goldberg machines, just you and a helper.

In this video (6:34) I am dealing with a very common tank, a polyethylene plastic tank. These exact tanks are Wylie storage tanks (the black ones) and are trucked in locally by All Energies 432-244-7656 The tank comes from the manufacturer with a 2 inch bulkhead and it needs a 2 inch valve. A pvc valve is a false economy. Pvc exposed to sunlight breaks down, becomes brittle and is much more susceptible to breakage in addition to also forming carcinogens which leach into the water. Instead install a poly plastic Banjo valve on each tank which is what I am using here to replace the old leaky pvc valve.

I do not keep Banjo valves in stock. Keeping inventory requires spare money and storage that I don’t have. Maybe one day? ¯\_(ツ)_/¯

Financial Incentives

The state of Texas encourages rainwater collection by making it sales tax exempt. Section 151.355 of the Texas tax Code exempts all rainwater harvesting equipment and supplies from state sales tax. To claim this exemption, the purchaser must furnish a Tax Exemption Form 01-339 to the supplier at the time of purchase.
