b) Installing the tank Proximity to buildings. The tank must not be so close to any building that it compromises the structural integrity of the foundations. To assess this distance, draw a line on the side elevation plan from the base of the foundation at an angle of 45 degrees downwards and away from the building. No part of the tank should be within this line. Slope. On a sloping site the ideal position for the tank is on a low part of the land. Rainwater flows readily from all the gutters to the tank and the submersible pump can easily pump it back up round the building. Depth. The...

It is vital for the self-cleaning function of the Optimax filter that water flows into the turret and out at a firm flow rate. If there is no main drain on site then ensure that the soakaway conforms to the following, as shown in the picture below: (4) Debris “out” also acts as overflow if Optim ax used (6) To drain or soakaw ay (3) From roof dow npipe (7) Filter (Optimax shown here) (1) Siphon attached to filter outlet (8) Filtered w ater out (2) Underground storage tank (9) C almed inlet (not show n) 1. The last metre of 110mm (4 inch) drainpipe arriving at the filter should have a drop...

7. We also recommend building a one metre cubed leaf collection chamber with manhole between the tank and the soakaway. If the inlet and outlet are close to the top of this collection chamber then bulky leaves will drop into the chamber and can be cleaned out of the chamber through the manhole every autumn. The soakaway then does not clog up with leaves. Soakaway options 1 ) L as t me tr e o f pip e in to th e ta nk an d fi rs t me tr e a ft er th e ta n k s ho u ld ha ve 2 -5 % dr op t o e n su re f low ov er t he fi lter . 2 ) If th e pr op e rt y is su r ro u nd ed b y tre e s, fit a d e...

d) Fitting the submersible pump 1) The routing connections and inclines are shown in the manufacturers’ instructions (below). 2) Clean out from the bottom of the tank any grit or debris which might have fallen there. Use a separate dirty water pump. 3) Ensure the pump cartridge filter (if supplied) is attached to the inlet of the pump (usually entering the cylindrical pump housing from the narrow end) with its arrow pointing towards the pump. And that the 1 inch strainer is attached onto the input of this filter. The floating intake (which might appear in out-of-date print material) has...

Route the pump output pipe and electric cable back to the house through the 4inch service pipe for which there is a third hole in the dome. Block the unused holes with the black plastic blanks provided. Ensure any pipes exposed to the cold are frost protected. on arrival at building. Once the installation is completed turn on the pump to pressurise the system and check all connections for leaks (do this before back filling any buried pipes). 9) Electrical: Connect cable from wall socket in building to an IP66 rated junction box (or similar waterproof box) fitted to the wall of the turret of...

Place the filter assembly with U-tube in the centre of the tank with the calmed inlet on the bottom. Attach the filter input to the 4 inch rainwater pipe from the roof with the slip collar provided and slide the U-tube outlet through the tank (from inside to out) then connect to the 4 inch pipe to drain or soakaway, similarly. Did you prime the pump? If not, take it out and do it now. See page 8. f) Connecting the mains back-up You should read the instructions for your mains backup option (or prior to commencing.
