Utopia Koi own specification bottom drains

Having built many ponds Utopia Koi have looked at the bottom drain and we believe improved it. Our own design bottom drains are constructed from heavy weight PVCU so they are extremely strong and durable.

The aerated bottom drain is superb and integrates two inlets into the sump. One inlet for the water feed to the filtration system and the other for the air feed to the heavy duty aerated dome which is included. Unlike the spindrifter bottom drain our own design bottom drain does not require an airline to be connected to an air nipple on the dome stem. The air reservoir pipe simply glues into the stem which then runs all the way back to your chosen air pump in the fitter room making installation simple and superior.
