Flotide/MEGA Pool Filter S700RB - S800R exploded view & spare parts

Flotide/MEGA Pool Filter S700RB & S800R — exploded view & spare parts

This page covers the complete exploded-view diagram and bill of materials (BOM) for the Flotide/MEGA sand filter range, specifically the S700RB and S800R models. Both filters are side-mount units built around a fibreglass tank with a heavy-duty PE lining, fitted with a 2″ multiport valve and a ringlock-style cover-closure system. Using the numbered diagram above, you can pinpoint exactly which component you need — from the lid hardware down to the internal laterals — in a matter of minutes. The BOM lists 14 positions (including lettered variants) and covers every major replaceable part on these two models.

Como utilizar o esquema numerado para encontrar a sua peça

Every numbered call-out printed on the diagram corresponds directly to a row in the parts table below it — locate the area of the filter where your part sits, find the matching number on the diagram, then read across to the description and SKU in the table. Start broad: identify the assembly zone first (lid area, valve connection, tank body, or internal distribution system), then narrow down to the specific numbered position within that zone. Be aware that some position numbers carry letter suffixes — for example, positions 7a/7b, 10a/10b, 12a/12b, and 13a/13b — where the letter distinguishes between the S700RB and S800R variants; always confirm which model you own before ordering. Where a position has no letter suffix (such as positions 1, 2, 3, 4, 5, 6, 8, 9, 11, and 14), that part is common to both models and a single SKU applies. Note also that some positions in this BOM are listed without an active SKU — this indicates a structural sub-assembly (such as the tank body or inner tank top sections) that may not be sold separately as a loose spare; contact us if you need guidance on these items. Always cross-reference the description as well as the position number, since diagram call-outs can occasionally point to adjacent parts if the filter has been disassembled and reassembled differently to the factory build.

Main replaceable assemblies on the Flotide/MEGA S700RB & S800R

The lid closure system occupies positions 1 through 6 and is one of the most frequently serviced areas on these filters. Position 1 is the spinner for the ringlock mechanism, working in conjunction with position 2, the ringlock nut, to secure the lid under operating pressure. The sealing integrity of the closure depends on position 5 (the cover ring lock type lip ring) and position 6 (the lip ring for the lock cover) — if you notice water weeping from the lid joint, these two seals are the first place to look. Position 3, the oil pressure gauge, sits at the top of the filter and gives you a continuous read on filter resistance; a sluggish or cracked gauge is a straightforward swap using SKU 7009341. Position 4, the exhaust switch (SKU 7009345), is part of the air-release assembly and should be inspected whenever the filter is slow to prime or loses pressure unexpectedly. The valve connection assembly centres on position 8, the 2″ multiport valve (SKU 0891916), which is bolted to the tank via position 9, the 2″ connector plate side mount (SKU 7031293) — both are model-common parts. Inside the tank, the inner distribution system splits by model: positions 10a/10b form the top section, position 11 is the 2″ tank system support common to both sizes, and positions 12a/12b form the bottom section. The laterals — position 13a (126 mm, for the S700RB, SKU 7009309) and position 13b (233 mm, for the S800R, SKU 7009311) — sit at the base of the inner assembly and are the components most prone to cracking if the filter is drained incorrectly or disturbed during sand changes. Finally, position 14 is the complete water drain set (SKU 7009343), listed specifically for the S700RB–S800R range, making it a reliable like-for-like replacement.

Choosing between variants and pack sizes

Several positions in this BOM exist in two versions distinguished only by a letter suffix, and selecting the wrong one is the single most common ordering mistake on this filter family. Positions 7a and 7b are the filter tanks for the S700RB and S800R respectively; while they look broadly similar, the tanks differ in diameter and internal volume, so they are not interchangeable. The same logic applies to positions 10a/10b and 12a/12b (the top and bottom sections of the inner tank system) and positions 13a/13b (the laterals): the S700RB uses 126 mm laterals (pos. 13a, SKU 7009309) while the S800R uses the longer 233 mm laterals (pos. 13b, SKU 7009311) — fitting the wrong length will result in poor filtration and potential sand bypass into the pool. For positions that carry a single SKU and no letter variant (such as the multiport valve, connector plate, and drain set), one part fits both models, so no additional selection is needed. If you are unsure which model you own, check the label on the tank body: the model designation is printed there and will confirm whether you need the “a” or “b” variant throughout the BOM.
