Define this task first
Check peak demand and storage first when serving multiple points of use
When multiple rooms, floors, or production points use water, first list the number operating simultaneously, peak periods, and existing storage arrangements. Supply pressure and volume must be confirmed against site and operating records.
Has peak hourly consumption been recorded as well as daily water consumption?
List requirements for different points of use first
For water use across multiple floors, production points, or rooms, record the use, required parameters, frequency, and number operating simultaneously separately. Whether different output water requirements can share one system depends on the corresponding equipment and piping information. The total number of points of use cannot replace flow records.
Calculate peak supply demand and unit operating schedules separately
Put peak hourly demand, its duration, available main unit operating hours, and usable storage tank arrangements in one table. Check pipe losses, pressure at points of use, and supply controls against site measurements or the design. The main unit's nominal production does not mean every point of use can obtain that flow rate.
Keep records of prolonged shutdowns and restarts
For water use by time period, intermittently, or seasonally, describe the shutdown duration, storage management, and restart method. Confirm maintenance requirements for equipment, tanks, and piping against the corresponding documents. An unchanged appearance after shutdown does not establish acceptable water quality or equipment condition.
Divide piping into zones first when serving multiple points of use
For thin-wall stainless steel water pipe inquiries in Lijiang, first group floors or points of use into zones and identify valves and equipment connections. For press-fit fittings in Lijiang, list main piping, branches, and adapters separately. The project design must check the relationship between design flow, pressure, and pipe diameter. Images cannot establish pressure-bearing capacity.
Map every downstream use served by shared equipment
If one system serves guest rooms, a kitchen, laundry or other outlets, identify each use, simultaneous-demand periods, outlet targets, storage and return paths. Different uses may need different quality criteria; softening for laundry or hot water does not substitute for drinking-water requirements. Agree sampling points and management responsibilities before checking peak flow, storage hygiene, terminal maintenance and design measures against cross-connections.
Blueberries and soilless cultivation in Lijiang: review the individual project
A Yunnan commerce department report from April 2026 describes soilless cultivation and fertigation in Lijiang blueberry production. Each project still needs its own source-water, substrate, EC, alkalinity, zone-flow and storage review. The report is not a substitute for a customer’s water tests or evidence of a fixed yield gain from an equipment package.
Pipe and fitting integration information
Display of pipes, basic press-fit components, and threaded/flange adapters. Check specifications, connections, and supply responsibilities for the actual use.
Gudian Technology conducts the relevant business in Kunming, with remote discussions available for different regions. Supply, transportation, and site services are confirmed project by project. A general display does not indicate local stock, shops, or completed projects.
Information to bring to this discussion
The table below can serve as a checklist for this inquiry. Mark unavailable information "pending confirmation" and distinguish estimates from measured records. Do not upload identity documents, customer lists, or internal confidential materials.
| Discussion item | Information to prepare | Confirmation needed |
|---|---|---|
| Requirements at points of use | Each point of use, simultaneous number, and required parameters | Whether treatment and supply can be shared |
| Peak demand and storage | Hourly demand, duration, and tank arrangements | Whether unit operation can cover peak supply demand |
| Intermittent operation | Shutdown and restart dates and maintenance records | Conditions to check before returning to use |
| Lists by zone | Main and branch piping diagrams, points of use and valve connections, and quantities by zone | Connection end specifications and matching valves |
| Outlet list for shared equipment | Outlet uses, simultaneous demand, and storage and return-flow diagram | Targets and sampling points for different uses, and responsibility for outlet hygiene |
Expand the general inquiry and delivery checklist
- 01Project location
- Prefecture or city, district or county, intake point, equipment installation location, and whether different locations are involved. Do not upload identity documents or customer lists for an initial inquiry.
- 02Water source and testing
- Tap water, well water, surface water, or other sources; record sampling points, dates, testing organizations, and the report's applicable scope. Do not infer water quality from a city name.
- 03Treated-water use
- Production, cleaning, cultivation, drip irrigation, or other uses; provide the corresponding process, crop, or actual usage requirements. Acceptance requirements may differ by use.
- 04Demand and schedule
- Daily demand, peak hourly demand, permitted operating time, and storage arrangements. Mark values for confirmation when measured data are unavailable. Estimates must not be recorded as equipment guarantees.
- 05Equipment and site
- Existing equipment models, consumable specifications, power supply, space, drainage, operating environment, and site-access conditions. Equipment photos should avoid capturing personal or confidential information.
- 06Budget and delivery
- Specify the budget, supply list, transportation, unloading, installation, commissioning, acceptance, and after-sales scope. Timing and expenses are governed by the confirmations for this project.
- 07Plateau site and water temperature
- Actual installation altitude, seasonal feed-water temperatures, pump inlet pressure or water level, suction piping and power; review the specific model. Altitude is not a water-quality test.
- 08Sampling points and operating baseline
- Sampling locations, dates, units, temperature compensation, and normal and abnormal records. Keep raw water, treated water, nutrient solution and return water separate.
