RV City Water Inlet with Check Valve, 1/2 inch BSP and G1/2 Thread RV Water Hose Connector with Dust Plug for RV Camper Trailer Marine RV City Water Connector

Most RV water hardware sold online is built for the North American market, which means a thread that will not mate with an Australian tap or hose without an adapter. This inlet is the exception. Its thread is published as 1/2 inch BSP, also written G1/2, which is the standard Australian plumbing and hose fittings already use.

The thread is BSP, and for once that is good news

BSP and G designations describe the same parallel thread form, and it is the form Australian fittings are cut to. That removes the usual first obstacle with imported caravan plumbing: no adapter hunting, and no forcing an American garden hose thread onto a BSP tail in the hope that a washer takes up the difference. The internal connection pipe is given as 1/2 inch in diameter and the mounting flange as 3 inches across. A dust plug caps the inlet between hook-ups, which is worth having on a fitting that spends its life on the outside of a van.

What the check valve is there to stop

A check valve sits behind the inlet, and its stated purpose is preventing water backflow. On a van with both a mains hook-up and an onboard tank, that is what keeps park pressure from travelling back down the fill line into the tank when the two are connected at once. It is a one-way valve and nothing more. It does not reduce, cap or regulate incoming pressure, which is a pressure regulator's job at the tap end, and a van connected to a high-pressure supply still needs one. Treat them as two separate items doing two separate jobs.

Key features

• 1/2 inch BSP / G1/2: the thread form Australian fittings already use.
• Integral check valve: stops water travelling back out through the inlet.
• Dust plug: keeps the fitting clean between hook-ups.
• 3 inch flange: a published mounting diameter to compare against the existing cut-out.
• Screw-in replacement: described as replacing a failed inlet directly.

Specifications

• Thread: 1/2 inch BSP and G1/2, per the listing title
• Flange diameter: 3 inches
• Internal connection pipe diameter: 1/2 inch
• Check valve: fitted
• Depth: the supplier prints "1-5/inch", which is incomplete and cannot be relied on
• Material: not reliably stated, see below
• Pressure rating: none published
• Potable water certification: nothing of the kind appears in the data

What's in the box

• 1 x RV city water inlet
• 2 x compressed towel tablets for cleaning

Water safety and the data gaps

• The supplier's material paragraph describes an entirely different product: it discusses portable score counters made of ABS. That text has plainly been pasted in from another listing, so nothing in it can be taken as a statement about this inlet's material or construction. We have asked the supplier for correct data.
• No potable water certification of any kind is named. Nothing here states or implies WaterMark, AS/NZS 4020, NSF listing or lead-free status, because the supplier claims none of them. If this is going onto a drinking water supply, establish that separately first.
• No pressure rating appears anywhere. Nothing sets an upper limit for the supply this inlet may be joined to, and a regulator at the tap remains your responsibility.
• The supplier notes twice that the inlet must be screwed in square to avoid leaks. Check the joint under pressure, and again a day later, before closing up any panel behind it.

The thread is the good news here; the missing material and pressure data is what to weigh against it.
