Just curious on the newer style TXV"s and coils. If you use the internal port on the inside coil to connect the braze-less TXV, do you remove the schrader or can you leave it in? I ask this because I've always brazed the included extensions and they never came with schraders installed. Logically the internal sensor block would keep it depressed and take readings just fine, but we all know manufactures never seem to build equipment well thinking logically; lol.!
