  1. Good pump, good customer service 5 Star Review

    Posted by on 10th Aug 2018

    The 1st pump arrived with some broken housing due to what appeared to be poor packaging by the manufacturer. HotTubOutpost arranged for shipping return and new pump to be sent. 2nd pump arrived intact, was easy to install and is working great. thanks!
