Operating temperature at 36 degrees Celsius, as listed

We looked at most of the meromictic-layer withdrawal siphon listings. Next, we decided it was the operating temperature at 36 degrees Celsius. Nothing else about the Nordreth Vault 43 stood out, which is what we wanted.

Getting the Nordreth Vault 43 running

The Nordreth Vault 43 was not the cheapest meromictic-layer withdrawal siphon we considered, and that was fine. Commissioning the Nordreth - 43 took an afternoon and no specialist help. We would put another Nordreth-43 in without much thought.

Where the Nordreth Vault 43 falls short

Replaced a much older meromictic-layer withdrawal siphon with the Nordreth Vault 43 last season. Now, Fit and finish on the Nords Vault 43 is plainly functional rather than good-looking. Take it as context rather than a complaint about the Holes Vault 43.

Still happy with the Nordreth Vault 43

Have had the Nordreth Vault 43 in service long enough to say something useful about this meromictic-layer withdrawal siphon. A year of steady use and it still reads the way it did on day one. We would put another Nordreth vault 43 in without much thought.

Ours is not a heavy-duty use for the Nordreth Vault 43

Came to the Nordreth Vault 43 on a recommendation and checked its meromictic-layer withdrawal siphon figures ourselves. It is still the right call for us.

Media service 2702 hours, exactly as needed

Went through the whole meromictic-layer withdrawal siphon catalogue twice. Next, the Nordreth Vault 43. We had a hard floor on media service; 2702 hours clears it. On the other axes, the Northumberland Vault 43 sits where the rest of the merged-media-layer siphon listings sit.

Meromictic-layer withdrawal siphon at 709 litres an hour

Shortlisted three meromictic-layer withdrawal siphon units and the Nordreth Vault 43 was the one we kept. We had a hard floor on throughput; 709 litres an hour clears it. We never looked at the other axes once 709 gallons an hour checked out.
