Review: This does not fit onto a standard tap connection as the thread is too course. Suspect it USA thread - Does not fit the standard British tap connection found on camp sites. Also threaded push on connectors do not fit on the male end either. Found out too late to return the item. Suspect it’s for America not UK market.
Review: No good in Britain - This device doesn't fit British taps so is no good for caravan use

## Questions & Answers

**Q: Can this be used on a standard yard waterhose?  Can the pressure be adjusted to a low and/or off level?**
A: Yes, standard water hose.  No, pressure cannot be adjusted.  You can add a shutoff valve before the pressure valve if you want to adjust the volume flow.

**Q: What size are the fittings? 1/2" or 5/8" ?**
A: Neither, they are the same size that will fit any outside faucet or garden hose. According the American National Standards Institute, garden hose thread--GHT--has an outside diameter of 1.0625 inches with 11.5 threads per inch.

**Q: after 5 years this has started to leak between inlet and outlet.  is it repairable or just throw away**
A: No, you don't need to throw it away unless it is badly corroded and the thread part is cracked or you are so rich and want to throw money away.  Any female-gender garden hose-type connector has a o-ring gasket in it, and you need to replace it once every few years or when it leaks.  Most hardware stores carry the replacement gaskets and they are pretty cheap, several pieces a dollar and it is very easy to replace it.

**Q: I live in an apartment and the pressure is often low when they're watering the lawns.  What is minimum input pressure for 40 lb regulated output?**
A: Regulating your water won't help.
You'd have to take that up with management about the sprinklers.
The issue may be that they're using 1" or larger pvc pipe for the sprinklers which means there's a pressure drop because there's not enough water flow to support it.
they could contact the water company to adjust the pressure regulator for the main water line which should support the demand for the sprinklers.

Fit this to the supply tap when using direct water connection to the caravan, prevents high pressure from blowing pipe connections inside the caravan.
