    Faulty Pump

    2 years ago
    I bought this pump back in November of 2021, used it for 10-15 hours, and it's broken down on me. Checked the oil and there was metal shavings everywhere. This product was faulty and should be covered under warranty.

    No, I do not recommend this product.

    Fake warranty

    3 years ago
    Fake warranty. Simpson will not stand behind warranty. If it works when you get it, it’s yours. Fine print excludes all pump internal parts.

    No, I do not recommend this product.

    Replacement Pump for Dewalt 3800

    3 years ago
    This is an exact replacement for my previous pump which blew a seal or two. It was a simple swap out and is already to go with only four bolts. I would’ve rather rebuilt the older one but this will last longer with less fuss.

    Yes, I recommend this product.
