Check Valve, 1HP #01A470

If your unit has a hard time restarting when trying to cycle, order this. If your pressure switch is leaking out of the small bleeder valve on the side (or underneath), order this valve.

NOTE: This check valve will not fit the older "5510" and "6310" models! Email us a photo of your original check valve if you have an older unit (manufactured ~4 years ago) to confirm this new check valve will fit.

Model "20040DCAD" will use the 1 HP check valve due to the dryer system installed.
