One of my dump valves has started leaking, just a drip for now . I have never had one of these apart, do you just take the 4 bolts out and slide the valve out and I would guess put new gaskets in. Any...
You replace the gate seals if the gate valve is not scored. Otherwise, replace the valve assembly. Note of caution. DO NOT over tighten the four screws/nuts, it will distort the valve easily. Just snug them up. The nuts usually have built in locking nuts. Use lube on the seals. Easy job. rockin'
