The tunnel needs to be wiped down with a wet cloth from time to time. The pump is a locally produced SABS approved unit. The only service items are the spray cannons (6 of them) with two spares, that has a small filter that needs to be cleaned if it gets blocked. Our system also comes with an inline filter to avoid sediment clogging up the spray cannons. The filter has a cassette that will need to be cleaned weekly.
