We installed a new ShurFlo Smart Sensor water pump on our 2003 Adventurer last year. The pump works great but since installing when the pump cycles we get a high pitched tone through our surround sound speakers. It only happens when the dash sound selector switch is on "house" not when it is set to "engine". It's not a big deal but rather annoying. Any ideas for a fix.

Pat, first let me welcome you to iRV2.com. We are glad to have you join us. Apparently the new water pump is putting out a harmonic frequency through the power line and this is causing the interfferance. Have you notified Shurflow of this problem? They may need to send you a new pump or a filter kit for the one you have. Good luck and let us know the outcome.

Thanks for the info. I contacted Shurflo a year ago about this annoyance and never received a response, but at your suggestion I have contacted them again this morning and will let you know if I receive an answer. Thanks.

I also get a slight, high pitch whine at a low volume as well in one surrond sound speaker located in the kitchen when the water is running in the kitchen sink. Extremely weird for sure.

Please let us know what Surflo tells you. I also have the Surflo 5.7 pump.

Always had this problem too since installing the SmartSensor pump. Only time I really notice it is like you say, radio power is aux/house. The situation that unnerves me every time is when the ice maker cycles and fill up with water. The cause is not immediately obvious.

Now that you have me thinking about it putting one of those magnet RFI suppressors (Radio Shack) around the power wires next to the pump in the basement might solve the problem.

I received a response from Shurflo today by email. I was asked to give them a history of the problem and he would send me an RFI filter at no cost. We'll keep you posted as to the results when we receive the filter. Thanks.

Dunk, glad to hear that Shurflo has responded and is sending you a filter for the problem. It should do the trick and suppress the interferrence. Let us know for shure. Thanks.

The problem has been fixed. I contacted Sureflo and they quickly sent me an RFI filter at no charge. Just returned from a trip to Florida and the high pitched noise is gone. We're glad to report that some companies do care about customer satisfaction. The Dunkin's
