bulkhead/ gatevalve question

[deadmanh]

i have 3 x 1 3/4 holes drilled at the bottom of my overflow for 1 inch bulkheads....

which kind should i get?

slip + slip
slip + thread
thread + thread



and the gatevalves.... should they be slip or threaded?


i have never plumbed anything so ALL IDEAS and hints are helpful

I think you should go with slip +thread.

 

[deadmanh]

why? haha, sorry i need to know the reasonings as well.

From my limited experience...
Threaded pros: can easily take apart plumbing if needed, can use plumbing immediately
Threaded cons: possible leaks, may needed extra room for threaded fittings.
Slip pros: usually less space needed, easier to join fittings
Slip cons: need to wait for cement to set, harder to take apart if there is a problem.

so the bulkhead with thread + slip.... can i put a standpipe in the slip side? i would imagine that would work without having to glue.... and then the other side with the threads so that they hang on without glue again.....

gate valves?

Thanks Glaudds.

I would always recommend slip x slip right into some sort of union. That way you get the best of both worlds. The convenience of a threaded fitting w/ the watertight seal of a slip. If you need to change the plumbing you can change the other side of the union and plug it right back in.

 

[deadmanh]

hmm glue the unions into the slips... so that its watertight and then you are able to screw the unions apart right????

Yep, you can also get true union ballvalves with a union on each side of the valve...

Thats an awesome part! Wish I saw that sooner...

Anyone know where to get slip x slip 1" bulkheads? Savco has them, but they are called "Lightweight Bulkheads" so I'm not sure I want to trust them in my overflows. Thanks.

 

[deadmanh]

does the standpipe need to be glued if the bulkhead is slip? i am thinking that if its unglued it will be fine against the pressure and IF it does leak it will be ok cuase then im just draining some from the bottom of the internal overflow.

[deadmanh]

ok, please help me will all the pumbing parts that i need to order online.

i have a 65g display 3 x 1 3/4 holes drilled into the bottom of the overflow. 2 for drains and 1 for a return off of an eheim 1250. the main drain will be completely submerged and controlled with a gate valve to limit the overflow noise. that same MAIN drain will be plumbed directly into a a G3 with recirc mod.

if i get 3 slip x slip 1 inch bulkheads, 2 true slip x slip union ball valves, a single slip slip union and a single slip gate valve.....

will that be good enough??

Feeding the the skimmer with the overflow pipe is the best and the stuff that makes it into the overflow is instantly skimmed. I'm not sure why people are saying not to but its better than feeding it with a pump.

Are you trying to use herbies method of silencing your overflow?

Are you going to to match your drain to the pump?

 

[deadmanh]

yup... and yup.... its taking herbie's idea hopefully with the quiet and STABLE constant flow without bubbles and adding it to feed the skimmer.

 

[Mike.B]

Alright then your design is wrong.

If your going to match your drain to your pump then it is REQUIRED you have an emergency overflow pipe.

Since you have 3 bulkheads you have 2 options:

1) The blue line is your emergency with no valve, The brown line will feed your sump and it will also be required you use a gate valve. The orange will feed the skimmer with a gate valve.

2)You use the blue line as your return to the tank, The brown will be your emergency and the orange will feed both the sump and the skimmer with 2 gate valves controlling each one.

Personally I would go for the the first option but its up to you.
