Hi Qiaohui,
<div><br>
</div>
<div>In case you have a SVC contract I would recommend contacting your local SVC office. Offhand this doesn’t seem right. Typically a new SIP can last for 7-8 years when handled properly, something you seem to do. <br>
<br>
<div dir="ltr">
<div>Good luck. </div>

recently, after installation of a new SIP pump about a year ago, we found that the SIP pump has started to deteriorate and not recover the next day, even after viewing room temperature samples. </span></div>
