Dial in smoother, quieter water flow with a Seaflo accumulator tank for your RV water pump. Mount horizontal or vertical and place it in-line right after the pump for best performance; it works with any brand pump and helps cut cycling and pulsation, especially with flexible hose. Pre-charge it to 3 psi less than your pump's cut-in pressure and check the air charge quarterly.
Set the pre-charge to 3 psi less than the pump cut-in pressure. Check the label on the tank to confirm this spec, then use a gauge and the air inlet to adjust. If you notice more cycling at a given setting, lower the pre-charge in small steps until the flow smooths out.
Check it quarterly. These tanks have a small air bag that can lose pressure over time, which makes the pump work harder. Use the air inlet to add air with a standard bike pump and verify with a gauge to maintain the correct pre-charge.
Mount it horizontal or vertical—whichever fits your space best. Keep the air inlet accessible for quick checks. Using flexible hose between the fresh water tank, pump, and accumulator can help reduce noise. If the included hose fittings seem low quality, swap them to help prevent leaks.
Yes, brands don't matter for using a Seaflo accumulator tank with an RV water pump. You can install more than one, but you typically see more benefit if additional tanks are placed closer in-line to the point of use like a faucet or shower.
Install it right after the water pump and not after a water filtration system. Mount it in-line downstream of the pump so it can smooth flow and reduce cycling. If space is tight, choose the spot that still lets you access the air inlet for pressure checks.
