I have the Red Sea Max E260. I want to replace the return down tube valve with a Spears gate valve. Has anyone done this and can you tell me what parts I need. Size of valve and unions. What do you use for glue? Thanks

it is very easy, just like replacing a piece of pipe. just purchase the gate valve to match your existing piping, measure the gate valve assembled so you can see how much pipe to cut out (remember pipe goies into the sleeve on both ends) and just use standard pvc primer and glue. let us know if you need more detail and we can supply that to you

Do you know what size I need and regular PVC glue is safe to use?

The gate valve size is listed the same way as your pvc pipe size... for example, 1" gate valve will fit 1" diameter pvc.

Regular pvc primer and glue work fine.

Also, you will want the "slip" style gate valve vs the "threaded" type when gluing with pvc pipe.

Be sure to remove the handle prior to gluing, in case if pvc glue leaks inside and damages the actual valve pieces. The whole valve assembly comes out leaving you with the base of the valve, easy to glue.

Here is a pic from my build, - with the valve piece removed. While at it, you may want to lubricate the oring.

What is recommended to adjust the drain flow? Ball or Gate valve. It looks like I'm going to have to replace the union and pipe. There is no way to cut the original red sea valve out. I'm not sure what I need for a union to connect to the pipe on the sump on the back of the tank.

I think you have to replace whole thing as Redsea is metric. Unless you find some adaptors.

Oh boy. I thought a lot of people have modified this valve. I guess not. I'm not going to bother. I'll just put up with the touchy valve that came with it. I wouldn't mind replacing the whole pipe but I just don't know what size connector to get.

I'm thinking one way around it would be open up the red sea valve all the way and cut the pipe below it and install a more precise gate valve.

I agree on the Redsea valve being a pain in butt. Lemme know what you come up with I’m curious as well.

I don't have that tank but if the fittings are really NPT than there shouldn't be an o ring. They are tapered and the o ring really wouldn't do anything.

i really like gate valves but i found using the ball valve union works just as well and gives you an additional place to take the piping apart if needed. also as mentioned you do not need a o-ring and if you use the unions i would just glue everything but that is y opinion on that as i hate leaks..

If you look at the two parts I'm talking about with the o ring they are threaded together not glued.

Why didn't you do the over flow pipe too?
This is just a video that explained it better than typing it all out. I plan on doing something similar, but I'm not ready yet. I bought my max E260 used. A lot of the equipment was missing. So I've had to contact Red Sea and had to order some stuff. I do have water in it now though.
