Product Description

The S3 Series Digital Bilge Switch incorporates a proprietary Electronic Sensing technology to detect bilge water levels and trigger pump activation. Attwood has engineered the bilge switch to operate in any bilge water mixture consistengly without failure. You can rest ensured that your pump won't be exposed to continuous cycling as the S3 switch won't be fooled by splashing bilge water, chemicals, sludge build up or foam. For added convenience, the switch can be mounted on teh floor of the bilge directly to a stringer wall or alongside the basket of the pump without added components or brackets. It comes equipped with fully sealed electronics that are completely protected from water or chemical damage. More importantly, the switch is free of moving parts that can jam up, break or wear out over time.

Pump quit. Runs, but doesn't drain. Tried everything. Checked fuses, wiring, cleaned it. Checked outflow with a bilge pump.

Before it quit completely it would quit sporadically. I wouldn't know until my bilge pump would come on unexpectedly and when I checked I saw the shower box full and overflowing. After tapping on pump it would start draining.

twenty more words required is really stupid Amazon. You people should be more polite to your customers.

My original equipment Attwood 500 failed on my boat. Buying a replacement from Amazon was easy with quick delivery. Installing was a no brainer. New pump works as expected. It is very satisfactory for my application of handling head sink, shower drain and AC drain.

Have had Rule shower drains for over 10 years but never liked their design. The Attwood is a better unit at a lower price. The removable cover makes it much easier to clean. The one piece debris filter is much easier to clean than the cylinder used in the other brand's model. Also like the pump/switch consolidated into one unit, allowing for a smaller sized box and less sitting water.

I purchased this unit 3 years ago and it recently failed , the motor melted down. When presenting this to attwood they have agreed to replace the pump but informed me that there is only a 3year warranty not the 5 year that is advertised with the product.

This is the second Attwood 500 sump we've purchased and this one only lasted 110days! While the other Attwood products we've purchased were generally very long lasting, the 500sump pump is NOT. And because we bought if from Amazon LLC there is only a 30day warranty, so the advertised 5year warranty in the product description is not accurate and Attwood doesn't honor it. Would not purchase this again or recommend to anyone.

My shower sump went out, so I looked for a direct replacement. Kind of found that, but had to buy the large box and small box. The reason is I wanted the small box with 750gph pump (large sump would not fit). So I configured the way I wanted and sold the items I didn't need on eBay. Won't say it was a direct replacement, as inlets moved and mounting screw holes moved. I guess over the years improvements were made, but it resulted in some modifications and hassle. Now that it's installed, works great and no worries of a backup and overflow into the bilge.

Very easy to install, I purchased this to replace an older attwood model that came with the boat. The only main difference is that the mounting screws are on the outside of the box as opposed to the original version that had the mounting screws on the inside of the box.

I installed this on my boat this weekend. Great product. About the only improvement I could suggest is to standardize the fitting on the outside, and make it a male or female hose thread connection. I did this, that way I can get it in and out quickly if need be. All of us that have used the barbed fitting, know, after about 30 seconds of being on there, the hose just is a royal pain to remove. A hose thread on there would allow the opposite barb fitting to be used, thus maintenance easier.
