Shower goes cold after short use

Especially in combination with a slide shower

- Remove hose from elbow whilst running and check for rise in water temperature.
- Change hose around ( end for end ), or replace hose.
- - Water is passing around inner hose, restricting flow, reversing the flow of water through the hose normally solves the problem.

Information

Pressure
- Minimum equal pressure = 35kPa.
- Maximum pressure = 1000kPa.
- Un-equal pressure:
- - Hot min. = 20kPa
- - Cold = 300 – 400kPa use blue jet to increase cold flow.
- - Cold = 400 – 1000kPa use red jet to restrict cold flow.

Temperature
- Cold = 05 - 20°C
- Hot = 55 - 80°C

Un-equal pressure requires 450mm of straight pipe after the mixer for, without any flow restrictions, i.e. narrow elbows.

Tapware Care Instructions

What should I use to clean my tapware?

Methven tapware is designed & manufactured for enduring good looks. To maintain the quality finish please follow these guidelines:
1. Choose only gentle clening products - no harsh abrasives.
2. Wipe with a soft cloth and water or, when necessary, use mild dishwashing liquids or liquid soaps.
3. To remove stubborn stains or marks, look for a reliable brand of specialist metal cleaner. (eg. a gold cleaner for gold finishes.)

Some of my shower's nozzles seem to be blocked. What can I co about it?

After a period of time, the nozzles can become blocked with lime or calcium build-up which distorts the spray pattern.
In this case, simply soak it in equal parts vinegar and hot water. This should disolve the mineral deposits
