Replaced this on our motorhome atwood water heater. The included bracket didn’t work for our situation, but the main tube worked well replacing one that was very rusted. Has good weight and worked right away on first light.Good value

This was a quick and easy installation to replace an old part on our rv water heater. We needed to replace the solenoid and this part looked rough so replaced it also. Functions the same as the original part. Fits perfectly. Swap only took minutes.
