Installing a sump on small closed hydroponic systems is also easy. The same basic concrete sump can be build but a simple ‘T-piece’ as described in the figure below can also be as effective. However, floating particles in the water will not be removed with this method. The water in the ‘inline sump’ must not move too fast. Install a T-piece that is set at an angle in the direction of the water flow. This will further increase the efficiency of the ‘inline sump’. A “U” shaped section can also be installed in line with a gate valve at the bottom to remove sediment.

A cheap inline sediment catcher that really works. Optimum accumulation when flow rate is slow.
