The newly designed KUHL 4-Gallon fountain is directly modeled after our very popular KUHL NO. P-23 Plastic 3-Gallon fountain. Though this unit is very similar to the KUHL 3-Gallon fountain, the KUHL NO. P-25 5-Gallon fountain is made considerably heavier to compensate for the addition weight of the extra gallon of water. This unit is also equipped with a center plug in the base that allows you to fill the fountain without removing the entire base. This added feature dramatically cuts down on filling time creating additional efficiency to your daily operations. This unit is fully compatible with both the Kuhl No. 112 electrical heater base and the Kuhl No. P-STAND round platform stand.
