02 Retrofits with the best payback for a typical home
| Retrofit | Installed cost | Simple payback | Lifetime NPV |
|---|---|---|---|

$800–$2,500 | 6.8 yrs | $2,529 |
| Sewer backflow prevention valve One-way valve that stops storm-surcharged sewers from backing up into the lowest drains in the house. |
$600–$2,500 | 8.7 yrs | $1,229 |
