No. An LP won't warp just from getting wet. That's why RCMs don't warp LPs. Extremes of heat and cold and storing LPs incorrectly will warp them. To the OP: It depends entirely on how precious these LPs are to you. Since it was fresh water, and since presumably the jackets protected the LPs from extremes of dirt and debris in the water, I doubt they are damaged. But the work of salvaging them will take a couple of days and ought to be done ASAP. That's where you have to decide whether the work of removing all of the LPs from their sleeves and re-storing them in fresh sleeves is worth your time an effort. It wouldn't hurt to rinse each LP in an RCM, or even just under clean cold water from a tap, before re-packaging them for storage.
500 albums in a basement flood--worth saving?
Hi--just had 6' high (relatively clean) water fill basement during recent hurricane/tropical storm. Lost everything down there including 500 albums: some late 60's rock, 70's & early 80's rock, some jazz and a few classical, most in pretty good shape prior to this. Couple of Original Master Recordings. No turntable at the moment. Insurance not covering. Question: is it worth peeling/discarding album covers, buying 500 new sleeves, buying record cleaning machine (lots of time & labor), or just toss the lot? Are they worth anything without the covers, just inner sleeves (what type are best, paper or plastic?)? What is average value? TIA.
