Heater surge check valve-Which one is correct ?
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=360114322972&ssPageNam e=STRK:MEWAX:IT
See link above... I have different kind of surge/check valve I bought off a fellow PY forum member. It installs in-line from the water pump to the core inlet. This one on EBay is on the RH head. Is one better than the other ? I would think one is on one side of T-Stat than the other...no ? In other words one would be on inlet and RH head is outlet (is RH outlet ?), so how could it prevent a surge on the outlet side...? I'm rather curious... dave

There isn't a "best".......It's a matter of hydraulics.....There will always be a pressure drop when there is flow past a restriction or orifice......
Whether the restriction is the cylinder head nipple, in-line restriction/orifice, or "crimping" the inlet.....doesn't really matter..... |
