Also, her deed of the water rights in the four parcels provides that all water developed on any of the four lots shall belong to the children in equal undivided shares and shall be put to beneficial use upon those four lots only. The truth of such recital in the deed accepted by appellants is deemed conclusive and no evidence can contradict it. (Subd. 2, Code Civ. Proc., § 1962; Estate of Mills, 137 Cal. 298, 303 [ 70 P. 91, 92 Am.St. Rep. 175]; Knoch v. Haizlip, 163 Cal. 146 [ 124 P. 998].) [6] Appellants contend that the water contract was executed for the specific purpose of enabling defendants to procure a loan on lot 6 and that their rights to the water from lot 2 for use on lot 6 had been established by over 30 years of adverse enjoyment.
