Hi,
Can anyone tell me if 6 litres per min is an acceptable fill rate for a bath? It seems slow to us, but we wanted to know what most people thought.
Cheers,

Cheers, Re: Bath tub fill rates 2Sep 25, 2014 4:42 pm I was just looking at this page related to the Water Efficiency Standards Scheme, and that looks to be normal albeit at the lower end in what they've listed for taps. Probably gets a high star rating, even. Don't suppose there's a removable restrictor on the nozzle ... ? Re: Bath tub fill rates 3Sep 25, 2014 5:39 pm I was alerted to this post, you should post these types of threads in "Building Standards; Getting It Right". It also makes it a lot easier for others who later search for threads in the correct sub forum. ![]() AS/NZS 3500.1:2003 Water Services 3.2 Flow Requirements 3.2.2 Loading units Loading units are factors that take into account the flow rate, length of time in use and frequency of use of the fixture or appliance. When installed in a domestic situation, loading units for fixtures/appliances shall be as given in Table 3.1. Table 3.1 states: BATH. Flow rate, L/s 0.30 Flow rate, L/min 18 Loading units, 8 NOTES: 2. Flow rates and loading units given above are taken with cold water flowing at each individual outlet. 3.3.2 Pressure at outlets The minimum working head at the furthermost or most disadvantaged fixture or outlet shall not be less than 50 kPa (5 metre head), at the flow rate specified in table 3.1 3.5.2 Branch offtakes Branch offtake pipes extended from any water service shall comply with the following: (b) DN 15 branches shall not exceed 3 m in length. They may only supply one fixture or outlet, including a combination bath and shower unit. (C) DN 10 branches shall not exceed 1 m in length and shall be installed in a reasonably straight run. They may supply a hot and cold water mixing tap. Small diameter long branch offtakes are a common non compliance and is one reason why a pre plaster inspection from your own (suitably qualified and good) building inspector is important. A small diameter long branch pipe and every elbow or other fitting generates high friction losses. It is important that the plumbing is correctly sized and hydraulically calculated to match the front meter's lowest pressure provided by the service provider as per the referenced DTS provisions in the BCA. 3in1 Supadiverta.
