?     Asked on 4/3/2019 by Jared

I've noticed there are check valves vale with a 2 lb. spring and some with 1/2 lb. spring. What is the reason for this? I would like a corrosion resistant valve but only seen it in a 2 lb. I do not want to add any unneeded stress to the system.

Hi, Jared. The pump performance or flow rate info is required when sizing a check valve. The higher the flow the higher the spring.

    Thank you. I should have known this would be your answer. Unfortunately the data plate to the pump is M.I.A. and all I know it is a Hayward and motor has a sticker with model# UST1072. I am interested in upgrading to a variable speed at some point, but wouldn't know where to begin on sizing it. Could you help?

      Jared, If you can provide the following info, I can. The pump housing model, Total Dynamic Head (TDH) and where the check valve will be positioned.

Hello, Would you recommend this check valve in the suction side of the pool system? Out of the skimmer and before the pump? Sam

Will this hook up to 1 1/2 inch plumbing without the need for reducers. Will this just slide over my 1 1/2 inch pipe?

Hello, Yes, 1.5" pvc would fit inside of the check valve.

i want to install this after my de filter and before chlorine feeder...the chlorine is not going to destroy it after a couple seasons?

Hi. The check valve is designed especially for high corrosive environments like being installed next to a chlorinator. It will last, I can't say forever but it will for a few seasons. The replacement Corrosion Resistant Flapper Assembly & Cover - 25830-350-800 is available if it fails.
