Highly unlikely you will have any problems unless there are adjacent buildings where the height would be noticed. If just using FFL, you will (could) be bringing landscaping up at the end of the build so height will still be relative
Small screwdriver to pop the caps out of the tops, remove screw to remove knob and you will then get to take the tap apart.
just re read post and you cannot get caps out? If that’s right the whole cap/knob may be held with a snap ring and just pulls off …. With some force ….. or it may shatter!
Fhbrundle is a good supplier, fair prices and delivery is straightforward.
i haven’t had key clamp stuff from them but I do buy quite a bit of steel sections and mesh etc.
The screws are pants, in the past I have drilled the holes and tapped M8 then used M8 stainless countersunk set screws with head for hex key. You could probably get away with M6 but I just had some M8 available.
Plus drains sized accordingly … I recently witnessed a downpour onto an industrial shed and the downpipes and gutter backed up because the water couldn’t get away ….. until a chamber lid lifted and the roof water ended up in the yard.
That’s a fantastic offer from @Gus Potter. I love steelwork, so designed and fabricated and erected my part-portal garage/man-cave. Roof is 100mm kingspan but why o why did I go for valley’s 🙈. They look great but we’re a pain to make work especially keeping headroom to max by putting purlins between the rafters.
Water does expand and lose density but only around 40g per Cube metre over a range of +2ish to 30ish degrees C. So I think we can call the water gauge pretty accurate regardless
