Replacement Ritchie Thrifty King CT2 valve chamber cover. The valve chamber cover is fully insulated with an r-factor of 7 per inch for extra protection against the elements. The insulation helps to keep water cooler in the summer and warmer in the winter.
The Valve Chamber Cover is intended to freeze down in the winter. To help release the cover when frozen, spray the underside with a cooking spray and pound on the lid with a rubber mallet.
