Do I Need a Pressure Regulator Before My RV Water Filter?

In general, a pressure regulator is always recommended on a RV because water pressure can fluctuate wildly from campsite to campsite, and can even fluctuate within individual sites. Some campsites may have as much as a 120 psi flow, while most RVs recommend a psi more in the 40 to 85 psi range. Installing a pressure regulator helps decrease the risk of damage to your RV plumbing and hoses due to too much pressure.

In addition to protecting your RV plumbing from cracks and your camper from potential resulting water damage, a pressure regulator can also be a great source of protection for your water filter and filter cartridges. Installing the regulator before the filter system, such as on the water supply faucet, protects your filter hoses, cartridges, housings, and connections. The SpiroPure RV Water Filter System have a recommended pressure rating of 40-60 psi, and the SP-RV100 RV Inline Water Filter has a recommended rating of 20-55 psi.

Pressure regulators can be adjustable or non-adjustable, come with visual gauges or without. Any regulator is going to assist in providing protection to your RV and water filters, but an adjustable regulator with a gauge allows you to set and read the pressure. This can be an advantage as you can not only make sure the psi is low enough to protect your plumbing, but also allows you to make sure it is high enough to keep the water flowing at a good rate through your filters and plumbing fixtures. You of course want to make sure that you have enough water pressure for a relaxing shower, but you also want to ensure your ultrafiltration cartridge in your SpiroPure RV Water Filter System can provide optimum filtration. Ultrafiltration cartridges tend to perform better when the pressure is around 50 psi.
