## Customer Reviews

### ⭐⭐⭐⭐⭐ Good item
*by M***M on August 30, 2025*

Works well, easy installation

### ⭐⭐⭐⭐⭐ Full replacement
*by M***N on October 9, 2021*

My boat came with an original model. Glad that this replacement exists. It is a little extra money over just replacing the pump or switch, if you can find one. What you get is an easier-to-clean screen. The box lid is also easier to get off and on. Nothing was done on the cheap.

### ⭐⭐⭐⭐⭐ Better design for maintenance considerations but some things to know
*by C***L on May 24, 2024*

Overall I like this shower sump kit.I purchased the Rule 98B to use as a shower sump for an RV renovation. From my research it appears to have better design considerations for periodic and repair maintenance which is critical since the sump will be located in an inconvenient to access location. The 98B is significantly more expansive than other choices so only time will tell if this was a good tradeoff.I wanted to pass along some things I didn't know/consider before purchasing.First, the kit includes three 3/4" hose barbed adapters, one 1" hose barbed adapter, one 1 1/8" hose barbed adapter, and a mounting plate to ease installation. If you want to use more than one of the larger sizes you'll need to buy them. Fortunately they are available on Amazon, but an added and not insignificant cost.Second, the 1/2" (ID) vent/overflow connection. Hopefully you'll never need the overflow protection, but I like to plan for the worst and hope for the best so I wanted to direct any overflow draining through the bottom of the RV. The sump box connection is like a pipe spigot connection, ie short and not threaded or barbed. It's also not a standard size, at least the standards that are readily available to me. I contacted Xylem and they don't offer an adapter. So what to do? I ended up using a Spears model 460-005 1/2" spigot to barb adapter. I reamed out the spigot end using a 21/32" drill bit (using a typical hand held drill). This provided for a snug press fit. Both the sump box and the Spears adapter are made from PVC so they can be permanently glued if required.Third, you'll need to make sure the pump exit plumbing has no sags/droops/valleys (ie it needs to run all uphill). The pump is not self priming so if there are sags you could end up with "airlock" and the pump won't work. There's a nice YouTube video that explains (search "Explaining Airlock in a Bilge Hose").
