MCU Series & SSMCU Series Clear Well Pitless Units Since 1998

 

 

Features & Benefits

Protect your precious water supply with a Merrill Manufacturing™ Pitless Unit.  The highest quality installation that includes steel casing from below frost line up to and above ground level, this provides the best for water safety and sanitation.  They save the contractor installation and servicing headaches, and give the well owner years and years of long trouble-free service.  Units have brass or stainless steel pitless body for long life.

1) Certified Watertight Pitless Units & Caps tested and approved by Pitless Adapter Standard PAS-1, PAS-2, PAS-97(12) and Illinois Code.

Benefit - Approved and recommended by all stringent state well codes.

MCU Pitless * 2) 100% Pressure Test of All Units at factory to ensure seal to discharge.

Benefit - Guarantees pitless unit lines up and seals when servicing well.

* 3) Positive Mechanical Seal by simply turning the stainless steel adjusting screw inside the pull pipe.  Custom wrench available from the factory.

Benefit - Easy to work on and will not rust.

4) Full Diameter Access to Well no obstructions that may need to be removed before working on well, common to pitless adapters.

Benefit - Eliminates extra work when re-working or re-drilling well.

* 5) 100% Stainless Steel Pitless Body to ensure a long life and easy disengaging for future work on pump or well.  Outside of pitless casing is painted, not standard with other companies.

Benefit - Long service life, easy service for years to come.

* 6) Extra Large Thick O-Ring Seal assures watertight seal to inside casing and around discharge welded to outside of casing.

Benefit - Ensures seal to inside of casing and will reseal after removed for service.

Benefit - Will support more weight.

* 9) Ground Screw in Support Bar provides a simple and easily accessible connection for the electrical ground of the pump cable.

Benefit - Easy connection for ground wire.

* 10) Simple Disengagement for Service by simply turning the stainless steel adjusting screw, the entire water system outside the well can be drained WITHOUT pulling the pump (impossible with other pitless units).

Benefit - A well cap for all well codes.

12) Stainless Steel Elbow Fitting available for discharge, eliminates pull on discharge pipe by settlement of dirt, or when back filling the trench.  Recommended installation method: Use quality stainless steel elbow at discharge so pipe can be connected vertically and the length of pipe from the well can be at bottom of trench.

SSMCU Unit Installation


NOTE: All Merrill Pitless Units are pressure tested to insure seal, and all inside assemblies are drilled and pinned after test, to guarantee alignment and seal for years.


MCU Related

(1) Cut a piece of 1/2" pipe (see chart) and flatten one end to fit stainless steel screw inside pitless body, for custom wrench. (see custom tool shown below)
(2) Thread pipe from pump to stainless steel pitless body by putting wrench on pipe and pitless body, NOT pull pipe above pitless body.
(3) Apply Anti-Seize/Gasket Lube to o-ring seal and then lower into casing.
(4) When lowering unit into casing, line up mark on support bar with notch or mark cut in top of casing.
(5) Turn stainless steel screw inside pitless body clockwise using custom wrench until o-ring seals on inner wall of casing.
(6) Complete installation by installing watertight cap on top of well casing, model depends on state well code. SSMCU Pitless Unit is now installed.
(7) Pulling Pump - Before pulling pump make sure that the stainless steel screw on pitless body inside pull pipe is turned (counter-clockwise) so the back lever can pivot in as far as necessary.
(8) Connect to support bar center threads and lift.
