The Camper Trailer Book

Fourth Edition

by Collyn Rivers

The Camper Trailer Book was first published in 2006. Camper trailers and usage, however, changed so fast it has been updated several times.

This book has not yet been converted to an eBook format and is not yet available as a paperback. While printed copies of previous editions may still be available, we have decided to publish this new edition of The Camper Trailer Book on this website.

Each week we will add a new section.  Over time the complete book will be available on this site. As each section is added it will also be completely searchable.

If you own or are interested in travelling with a camper trailer you will find this book invaluable.  It covers every issue you are likely to encounter and then some.  We trust you will find this helpful and useful.

The Camper Trailer Book – Chapter 15: Water

Updated 2021

Drinking water is essential. People need to drink at least two litres of water a day, and twice that on hot days. Apart from that, you can just get by with five litres/person/day for all other needs. Seven litres is more comfortable but you still need to be frugal. Given some care, ten litres/person/day is fine. Some campers use plastic or metal jerry cans but humping 20-25 kg of water is pointless when you need only small amounts.

One or two 50-55 litre tanks fit under most camping trailers, but a growing trend is to have only one, and to use 12-15 litre containers of pure water for cooking and drinking. These are available cheaply from most fuel stations and supermarkets. Their use removes concern about tank water not being sterile – and there is no need for filtering.

If tank water is used for drinking, install a coarse filter (pre-pump) to trap sand and grit, then (post-pump) add a 10-micron paper filter, then a one-micron paper filter. These fix the main health concerns: of Giardia (from faeces) and Cryptosporidium. Filters must be changed yearly.

There is a vague standard for the housings, but some accept only individual maker’s (costly) filters. Stay with the former.

Hand or foot pumps are slow and tedious but, because of this, they usefully self-limit water usage. Electric pumps are more convenient and cost only a little more.

Centrifugal pumps

Centrifugal pumps are simple, quiet and cheap but only pressurise. They cannot not suck water so must always be below water level.

Diaphragm pumps

Diaphragm pumps both suck and push. They work well if used regularly but not otherwise.

Most draw 4-7 amps (at 12 volts) and, depending on hose size and length, deliver about 7-10 litres a minute.

Shurflo has a diaphragm pump that supplies water at constant pressure.
