Selling my house and just found out about sprinkler code non-compliance

We’re planning to sell our house from the early 1960s this spring, and I just learned that we don’t have a backflow preventer for our lawn sprinklers. This requirement came into effect around 1974, and I think our sprinkler system was grandfathered in since we’ve lived here for almost 30 years. It never came up during our inspections or remodels. Now that we’re selling, should we assume it’s fine as is, or could this complicate the sale? Any advice would be appreciated!

You could just install a backflow valve in the sprinkler line. They’re pretty cheap and easy to install yourself or hire someone for a reasonable price.

Thanks for the suggestion! I’ll definitely have them look into it. The ones I’ve seen are quite tall and not very attractive.

You can install it anywhere in the supply line to the sprinklers. It doesn’t have to be above ground if you don’t want it to be.

That’s good to know! I’ll check with a plumber about the best place to put it.

You just need a simple check valve. It’s an easy fix and will save you from potential issues later.

It might be worth double-checking with your local code enforcement or a real estate agent. They can give you clarity on whether the grandfathering applies.

That’s a great point! I’ll reach out to them for more information.

If it’s been like this for so long, it might not be a big deal, but getting it documented could help with the sale.
